Question 547218
Suppose that theta is an angle in standard position whose terminal side intersects the unit circle at (-3/5, -4/5). Find the exact values of cos theta, sec theta, and cot theta.
**
Given coordinates place the angle in quadrant III where cos<0, sec<0 and cot>0.
You are working with a right triangle with adjacent leg of -3/5, opposite leg of -4/5 and hypotenuse=1
..
cos theta=-3/5
sec theta=-5/3
cot theta=3/4
