i need to find the radian measure of four angles in standard position that are coterminal with the given angle in standard position.

1. and i am given ∏(pi) / 4 pi over four

2. 7 ∏ / 5 seven pi over five

3. - ∏ / 6 negative pi over six

now i have the answer to the first one but i want to know how to do it the first one is

9 ∏ / 4 ; 17 ∏ / 4 ; - 7 ∏ / 4 ; - 15 ∏ / 4
