Question

complex numbers in polar form: the angle θ can be in degrees or radians, so do I have to change the mode on my calculator every time?

Answer 1

...anyone? Yes? No?...

Answer 2

When you get to any kind of trig problems, especially polar coordinates, it's best to have your calculator set to radians.

Answer 3

The best thing to do is memorize the unit circle, or have the degree to radians formula handy, most problems in a math book will deal in the standard easy to remember stuff.

Thanks!
