Issue 26: Japanese Review ... not sure what chapters but I remember when I wrote all this

Sorry its not rotated. I need to figure out how to rotate before uploading.
Also, please tell me if there is any known mistakes. I am also going to create one for the basics of trig.
Note: I will most likely update weekly with trig these coming days. I have problems with trig and will create plentiful for myself, which means more postd th. If there is anything you want to upload up here, please tell me @ yao6488@gmail.com.
Also, give an name so I can credit (please no unreasonable names, like an celebrity, if you're not...if you give me a silly name, I'll just post you the email domain name instead if its proper, otherwise I won't post it up... just saying, if you give me a whole name, I'll probably just but the last name. If you give me a first name, I'll post that). Also please credit the textbook you have used if you can. I will allow gaming names such as Lucky6488 and ReiRay but nothing like NanaMizuki, I don't mind NanaMiz4eva or something but nothing that isn't right.
Damn that is a bad date... You'll understand if you know 4 in Chinese or Japanese and the word for death

Issue 25: Analytical Geometry (Alg 2/Trig)

It's been a long time since I updated.

Well, I created one for Alg 2/ Trig.

This time I have some problems using equations in google doc/word so I had to create a website.

It's a crappy website I made in 10 minutes, don't complain. 

https://sites.google.com/site/amuletterei/nyan-cat-express-review

The link, Test 23 is there.
Images don't show up... They are important images. Teaches you a lot.
But I'll still tell you ppl when It's updated okay :D

Analytic Geometry:

The Circle

The Parabola

The Ellipse

Transformations of Ellipse

Hyperbola and its transformations

Identifying Conic Sections

To review:

Distance and Midpoint Formulas

-Pythagorean Theorem:

If the length of the hypotenuse of a right triangle is c, and the lengths of the other two sides (legs) are a and b, then .

-Converse of the Pythagorean Theorem:

 If the lengths a,b, and c of the sides of a triangle satisfy the equation c²=a² + b²then the triangle is a right triangle and c is the hypotenuse

-Distance Formula

The Distance between the points P₁( x₁ , y₁ )² and P₂( x₂ , x₂ )²

P₁P₂=

-The Midpoint Formula

The midpoint of the line segment joining P₁( x₁ , y₁ )² and P₂( x₂ , x₂ )² is

-Circles

Conic Sections (Conics): Plane curves with 2nd degree equations

Circle: the set of all points in a plane that are a fixed distance, called the radius, from a fixed point, called the center

Equation of a circle: The circle with center (h,k) and radius r has the equation

Sliding a graph to a new position is called a translation.

-Parabolas

A parabola is the set of all points equidistant from a fixed line, called the directrix and a fixed point not on the line called the focus.

-Ellipse

Each of the fixed points is called a focus (plural: foci) of the ellispe. If the foci are F₁ and F₂, then for each point P of the ellipse, PF₁ and PF₂ are the focal radii of P.

The center of an ellipse is the midpoint of the line segment joining the foci. The major axis of an ellispe is the chord passing through its foci. The minor axis is the cord containing the center and perpendicular to the major axis.

 

Hyperbola

The set of all points P in the plane such that the difference between the distances from P to two fixed points is a given constant.

Focus: The fixed points

Focal Radii: PF₁ and PF₂

Issue 24: Chemistry

Well. I admit I know many of my other classmates take Biology but I was placed in a chemistry class so this would help you ppl eventually~
Actually I don't mind if people give me theirs. All they should do is email me at yao6488@gmail.com
And tell me who should I put as the person who made it. It could be a fake name but Idc. It's not mine and I want to give credit. Also I'm sorry people. I don't take French anymore... I take Japanese now~ :# much to my own selfishness.
Well... Here I go...
 From the Chemistry Reference Tables Workbook by Topical Review Book Company:
1 mole (mol) is 6 x 10^23 atoms, molecules, or ions.
Polyatomic Ions: charged particles composed of two or more atoms. These are quite stable.
The halides are negative ions formed from Group 17 elements >> halogens
Soluble ionic substances (SALT) dissolved in water will conduce electricity >>>> eletrolytes
The notation:
(s) >>>>>> Solid
(aq)>>>>> Liquid
A solution is homogeneous since the solute is distributed uniformly throughout.
Homogenous means of same/similiar nature.
The dissolved solution can't be separated by filtration
The presence of solute raises the boiling point of the solvent and lowers the freezing point of the solvent.
Pressure has an effect on solubility of a solid in water. Increase pressure, the more soluble, less pressure less soluble.
The outermost energy level is the valence level as how many electrons in the valence level is the valence electron.
Any energy level higher than the ground state is referring to the excited stated.
When an excited atom returns to the ground state, energy is release in teh form of quanta, forming a bright line spectrum
To determine the # of neutrons in teh nucleus of an atom, subtract the atomic number from the mass number.
Electronegativity of an atom is the measure of the relative ability of that atom to attract bonding electrons to itself.
Atomic Radius is an estimate of the size of an atom or the distance from the center of the nucleus to the edge of the atom.

From the Barron's Let's Review Chemistry The physical setting and etc.

Neutrons add mass to an atom but do not change the atom's charge.
Isotopes:
A molecule is the smallest identifiable sample of a substance
The noble gases are isolated atoms and are monatomic molecules
Every molecule can be represented by a molecular formula which symbols of the element is succeeded by a subscript that indicates the number of atoms present.
The loss or gain or electrons by an atom results in the formation of an electrically charged particle called a ion.
Chemical formula is an important part of the language of chemistry because it tells us something about the composition of an element or a compound.
Binary Compound: exactly two elements. Ions in ionic compounds do not exist as individual molecules.
An ionic formula is the chemical formula for an ionic compound.
Molecular Formula: the number and type of atoms that are present in a single molecule of a substance.
Empirical Formula: the ratio of elements present in the compound.
Structural Formula: show how the atoms in a molecule are bonded to one another. This is usually to represent chemical bonds by lines and unshared pairs of electrons by a pair of dots.
Real Charges:
Apparent Charges:
Oxidation state: The oxidation number of every atom in a free element is 0. Free element meaning that an element is not combined with another element.
An atom becomes more stable when it acquires the electron configuration of a noble gas.If the valence level of a stabilized atom is the first principal energy level, it would contain TWO electrons, otherwise it will contain EIGHT electrons.
In MOST case, we say that the bonding atoms have obeyed the OCTET RULE.
Octet Rule: The octet rule is a bonding theory used to predict the molecular structure of covalently bonded molecules. Each atom will share, gain, or lose electrons in order to fill outer electron shells with eight electrons. For many elements, this rule works is quick and simple to predict the molecular structure of a molecule.
Read this for the exceptions: http://chemistry.about.com/od/chemicalbonding/tp/Exceptions-To-The-Octet-Rule.htm
Certain pairs of atoms do not have a strong tendency to transfer electrons between them. These atoms share electrons between them. Electron sharing always occurs in pair and the two atoms may normal share 1,2, or 3 pairs of electrons. The atoms bond together because the shared pair or pairs belong to both atoms. This is COVALENT BONDING.
However, the sharing of the electron pair is not always the same in both molecules. If the pairs of electrons are shared equally by both atoms. That is nonpolar covalent bonding. You can look at the structural formula. If it is symmetrical, it is nonpolar covalent.
If it isn't symmetrical it is polar covalent bonding. This is because the electrons are not shared equally.
The Lewis Dot structure is used to see which atoms are present AND how they are joined

That's all for now.

Please do not write that u r someone ur not.
>:c
I mean like don't write that you are an idol unless you really are an idol. Use a proper user name please. That will annoy me if you do write that.

Question!!!!!!!!!!!!!!!1

Are we suppose to post test review stuff on this site? Or anime/manga stuff? Or anything?

Issue 23:Unit Conversion

The first one I'm doing this school year ^.^
This one is a simple one, it's easy to understand but also easy to make mistakes.
Okay....

Convert: 1000ft-->meters
Note: 12in=1 ft, 1in=2.54cm and 100cm=1 meters
We are going to use unit multipliers, since it's the easiest way to solve this unit conversion problems.

1000ft  x   12 in  x  2.54cm  x    1m      = You calculate the answer
    1            1ft           1in        100cm
     ^            ^                                ^
Why 1?,      We put what we         Never change the meaning of the question
It's because     try to cancel out      1m is 100 cm, it can never be 1cm = 100m
We don't want  the units.                 That would be incorrect! But do try to cancel out the equation
to change          In this case, it's
the meaning        feet
of the numerator

The correct answer is 304.8 meters


Cubic and Squaring >>> This is more complicated to remember. Well it's okay....

Convert 10m^3 to yd^3
Note that 1m=100cm, 2.54cm=1 in, 36 in= 1 yd. And that ^3 is the exponent (to the power of three)

  10m^3   x   (100^3)cm^3   x         1in^3        x        1yd^3     = Calculate the answer
       1                  1m^3             (2.54)^3cm^3      (36)^3 in^3

Since we are doing cubics, you have to cube the multiplier numbers.( For all the multipliers!! The original should be cubed already, we do not need to do that again, otherwise it's incorrect!!!)

The answer should be around 13.08yd^3

Okay, this last question is a little difficult since it needs to convert the time and distance
(I took this question from somewhere and reword it)

A man ran 100 yards in 9 seconds. Would he be speeding if he was running in the neighborhood with a speed limit of 35 mi/hour??
100yds =around 11.11 yd/s
    9s     

35 mi  x    1hr   x   1min  x  1760yd  =  154 yd  = around 17.11 yd/s
 1 hr       60min       60s         1mi            9s

I did the time first here            then distance here
The answer was to match the yd/s
Therefore he wouldn't be speeding

Issue 22: Geometry...

Sorry a little numbering problems
Ok... a little more Geometry
By Miyu.
A = C
B     D

Extremes: A and D
Means: C and B
Cross Products: The product of the means and the product of the extremes. In other words, if A/B=C/D
then ad=bc

Similarity Statement: A statement indicating that two polygons are similar by listing their vertices in order of correspondence. (In the same order)
Theorems:
1.Through a line and a point not on the line, there exist exactly one perpendicular line to the given line.
2.The perpendicular segment from a point to a line is the shortest segment from the point to the line.
3.The perpendicular segment from a point to a plane is the shortest segment from the point to the plane.
4.If two lines are parallel, then all points on one line are equidistant from the other line.
5.If a diameter is perpendicular to a chord, then it bisects the chord and its arcs
6.If a diameter bisects a chord other than another diameter then it is perpendicular to the chord.

Inscribed Angles: An angle whose vertex is on a circle and whose sides contain chords of the circle.
The arc formed by an inscribed angle is the intercepted arc of that angle.
The measure of an inscribed angle is equal to half the measure of its intercepted arc.

Hi

Hi....This is a test!

Issue 21: Geometry

By Miyu:
WELL... It is the hot humid summer but we still have to keep studying to keep up the good work. More Geometry （ｏ。ｏ；）☆⌒(*＾-°)v
So... ISSUE 21: Geometry. 
Arc Length: Distance along an arc measured in linear units
 <<< Here's a picture I found on google that could help you. (This isn't a photo made by me, just a good photo to use)

Sector of a circle: The region inside a circle bounded by two radii of the circle and their intercepted
arc.
 <<<More good pictures and information.
Incenter of the triangle: When all 3 angels of a triangle are bisected, the point of concurrency.
If a line bisects an angle of a triangle,  then it divides the opposite side proportionally to the other 2 sides of the triangle.
If perpendicular bisectors are drawn for every side of a triangle, the point of concurrency is the circumcenter of the triangle.
The circumcenter lies at the center of the circle that contains the three vertices of the triangle. Any circle that contains all the vertices of a polygon is called a circumscribed circle. Any Polygon with each vertex on a circle is an inscribed polygon
Theorem 39-1: If one side of a triangle is longer than the other side, then the angle opposite the first side is larger than the angle opposite the first side is larger than the angle opposite the second side.

Theorem 39-2: If one angle of a triangle is larger than another angle, then the side opposite the first angle is longer than the side opposite the second angle.

Theorem 39-3: Exterior Angle Inequality Theorem: The measure of an exterior angle is greater than the measure of either remote interior angle.

Theorem 39-4: The sum of the length of any two sides of a triangle must be greater than the length of the third side.

Postulate 19: If two polygons are congruent, then they have the same area.
Postulate 20: The area of a region is equal to the sum of the areas of its nonoverlapping parts.
Theorem 40-1: Hinge Theorem- If two sides of one triangle are congruent to two sides of another triangle and the included angle of the first triangle is greater than the included angle of the second triangle, then the third side of the first triangle is longer than the third side of the second triangle.
Theorem 40-2: Converse of the Hinge Theorem: If two sides of one triangle are congruent to two sides of another triangle and  the third side of the first triangle is longer than the third side of the second triangle.

**EDIT**
Measure of central angle = Measure of arc. 
(A friend assured me... LOL)
