FC: Math 172 Review

1: A Math Review | I hope you enjoy this math, review ! & remember to do good work !

2: Notes | The Law of Sines (or Sine Rule) is very useful for solving triangles: | So if you divide side a by the sine of angle A it is equal to side b divided by the sine of angle B, and also equal to side c divided by the sine of angle C

3: Lets see what you remember!

4: Unit Circle Notes | The "Unit Circle" is just a circle with a radius of 1. | The unit circle is the circle whose center is at the origin and whose radius is one. The circumfrence of the unit circle is 2 . An arc of the unit circle has the same length as the measure of the central angle that intercepts that arc.

5: What do we remember about the unit circle

6: Math is BEAUTIFUL

7: Notes | Soh... Sine = Opposite / Hypotenuse cah... Cosine = Adjacent / Hypotenuse ...toa Tangent = Opposite / Adjacent

8: The Law of Consines

9: Notes | The law of cosines for calculating one side of a triangle when the angle opposite and the other two sides are known. | The law of cosines is useful for finding: the third side of a triangle when you know two sides and the angle between them (like the example above) the angles of a triangle when you know all three sides (as in the following example)

10: Your friendship, love and well wishes will be remembered always.

11: True Love Lasts Forever && so does math
