Determine two coterminal angles (one positive and one negative) for each angle. Give your answers in radians. π/4 and -3π/4

Answer 1

Hey Ashley!

A coterminal angle is an angle that matches another angle (meaning you add/subtract 2 pi or 360 degrees to an angle to get a coterminal angle).

For pi/4, you can have 9pi/4 for the positive and -7pi/4 for the negative

For -3pi/4, you can have 5pi/4 for the positive and -11pi/4 for the negative

Answer 2

π/4=45°

-7π/4=-320°
