I need help trying to solve trigonometric identity problems
I just need help if someone could break it down step by step how to solve for:
if cos of theta is -3/5 find csc of theta

CosTheta=-3/5
so you know the adjacent side to Theta is -3, and the hypotensue is 5.
That makes the opposite side =-4,or +4
so, sinTheta=4/5 or -4/5
secTheta=-5/3
cscTheta=1/sin= 5/4 or -5/4
TanTheta=4/3 or -4/3
Theta is in quadrante II or III
