Question

Is -630 degrees in radians -7pi/2?

Answer 1

@mathmale Did I do get this right?

Answer 2

Would love to help, but I have a social engagement right now. If no one else has helped you by later this evening, I'll gladly get back to you. So sorry.

Answer 3

Yes, it does seem to me that -630 degrees is equivalent to -7pi/2.
If y ou add : 360 degrees 4pi/2

You get -270 degrees -3pi/2 radians,

which is true.
