suppose theta is an angle in standard position whose terminal side lies in quadrant IV. If sin of theta = -4/5 find the value for cot theta
***
In quadrant IV sin<0, cos>0, cot<0

note: a shortcut method is to recognize you are working with a (3-4-5)reference right triangle, then, cosx=3/5.
cotx=cosx/sinx=3/-4=-3/4
