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
