Determining angles and the 6 trig functions?! D:

1. The problem statement, all variables and given/known data

3. The attempt at a solution

No attempt, don't even know where to start. I get a point... I can draw a triangle out of it. I can figure out the X and the Y.

I know the 6 equations... Sin, Cos, Tan, and the opposites Cosecant, Secant, and Cotangent...

I know sin = y/r, cos = x/r, tan = y/x, and flipped for the opposites of them.

And now I'm lost... :'(

Looks like these points are on the unit circle. So, what is the radius of the unit circle?

Yes, and you are given x and y for each. Since this is on the unit circle, r= 1.
