Question

How do you find co terminal angles (find one positive, and one negative)?

`330 degrees`

Answer 1

If you are measuring the angles in degrees, you can add and subtract multiples of `360^o`. If you are measuring in radians, add or subtract multiples of `2pi`.

Explanation:

For example, coterminal to `30^o` would be `390^o` or `-330^o`.

Coterminal to `pi/3` would be `pi/3 + (6pi)/3 = (7pi)/3` or `pi/3 - (6pi)/3= (-5pi)/3`.
