## anonymous one year ago Hey guys I will Medal and Fan, I have a test tomorrow and I was wondering if somebody could run me through on how to find the 6 trig functions from the Unit circle?

1. anonymous

I know mostly but I need a review.

2. anonymous

@phi

3. anonymous

yay @Nnesha

4. anonymous

can you help??

5. Nnesha

2 ways) learn the pattern /memorize familiar with 45-45-90 / 30-60-90 triangle i have 10 mints then i gtg somwhere :D

6. Nnesha

btw are you allowed to use unit circle ?

7. anonymous

ok I know how to get sine and cosine but what about the other 4

8. anonymous

no but I know how to get the coordinates without it

9. Nnesha

ohhh i know what you are asking now they are reciprocal of each other let's say sin is 2/3 then csc would be 3/2

10. anonymous

ok cool then the only thing i need is tangent, how do i get tangent and cotangent

11. Nnesha

$\large\rm sin \theta = \frac{ 1 }{ \csc \theta }~~~\cos \theta=\frac{ 1 }{ \sec \theta }~~~\tan \theta =\frac{ 1 }{ \cot }=\frac{ \sin }{ \cos}$

12. anonymous

can you kind of quiz me, like what is the tangent of 45 degrees? just a few questions want to make sure I got it down

13. Nnesha

|dw:1440369354201:dw| tan = sin over cos

14. Nnesha

sure!

15. anonymous

ok hit me!

16. Nnesha

$$\huge\color{red}{\rm Q:1}$$ $\tan( 120)$ $$\huge\color{red}{\rm Q:2}$$ $\sec(270)$ $$\huge\color{red}{\rm Q:3}$$ $\csc(360)$

degrees*

sorry but I have to go, I get this stuff though , thanks for helping me review. you helped a lot I will medal you if you medal me.

19. Nnesha

what did you get ? :) ;o
