### Transcript of "Angel"

1. 1. Trigonometry for Dummies BY:ANGEL IGLESIAS
2. 2. Sin A= OPPOSITE = B HYPOTENUSE C Cos A= ADJANCENT = D HYPOTENUSE C Tan A= OPPOSITE = B ADJACENT D Tan A= Sin A Cos A A B C D
3. 3. <ul><li>Angles can be measured in two different ways- degrees or radians. </li></ul><ul><li>Degrees can be converted into Radians by multiplying the degrees by </li></ul><ul><li>π / 180 Now make sure that π stays in the solution. </li></ul><ul><li>A Radian is the measure of a special central angle whose intercepting arc is the same as the circle’s radius. </li></ul>
4. 4. <ul><li>A unit circle is on a coordinate plane with its center at the origin with a radius always of 1 Sin and Cos can be located in the unit circle (x,y) (Sin,Cos) Tan is Sin over Cos in a unit circle </li></ul>
5. 5. <ul><li>On a unit circle a triangle is formed by an initial side which is always on the x-axis and the other side is called the terminal side in which the angle ends The reference angle is the acute angle formed by the terminal side and the initial side which are formed by a counter -clockwise rotation A coterminal angle is also like a reference angle but instead of just being from the initial side to terminal side, it goes all the way around </li></ul>
6. 6. This is a trigonometric function of the angle through their coordinates. The format is (cos, sin).
7. 7. <ul><li>Sin θ = 1/Csc θ </li></ul><ul><li>Cos θ = 1/Sec θ </li></ul><ul><li>Csc θ = 1/Sin θ </li></ul><ul><li>Sec θ = 1/Cos θ </li></ul><ul><li>Tan θ = Sin θ/Cos θ </li></ul><ul><li>Cot θ = Cos θ/Sin θ = 1/Tan θ </li></ul>
8. 8. <ul><ul><ul><ul><ul><li>THE END </li></ul></ul></ul></ul></ul>
