Question

If the point (5/13,12,13) corresponds to an angle theta in the unit circle, what is cot theta

Answer 1

I think you meant to type (5/13, 12/13) right?

Answer 2

yeah, my b

Answer 3

that's ok

Answer 4

for any point (x,y) on the unit circle we can say

tan(theta) = y/x

and

cot(theta) = x/y


Note: tan is only defined when x is not zero, cot is only defined when y is not zero
