Hi,

This is my first post and I'm really sort of stumped trying to do my homework here - it's to be in for tomorrow and I was out when it was being explained...

The sum is:

If tanA = -1, find the two values for angle A, where 0degrees <= A <= 360degrees

If anyone could explain how to do it, at Junior Cert level (Ireland), I'd really appreciate it!

I don't know how to get certain symbols

Thanks in advance!
