Find all angles which satisfy the following equation. (Use the parameter k as necessary to represent any integer. Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION.)

cot() = 0

Solution

cot() = 0

= pi/2 + 2pik where k is an integer

Solution: k =0 ; = pi/2

k=1 ; = 5pi/2

k=2 ; = 9pi/2 and so on

= pi/2 , 5pi/2 , 9pi/2 .....
