Express each value as a trigonomic function of an angle in quadrant I: Cot(-660)

Answer 1

adding 720º to our angle would give us a coterminal angle.
-660 + 720 = 60
so cot(-660) = cot 60
= 1/tan60
= 1/(√3/1) = 1/√3

Answer 2

Use the given information to determine the exact trigonometric value of csc(theta) if cot(theta)=-8 and 3pi/2 < theta < 2pi
