Find the exact value of the remaining trigonometric functions if
cosA=(-3)/(5) and sin A<0
**
cos and sin functions are both<0 only in quadrant III
given information show you are working with a 3-4-5 right triangle in quadrant III
cosA=-3/5 (given)
sinA=-4/5
tanA=sin/cos=-4/-3=4/3
secA=-5/3
cscA=-5/4
cotA=3/4
