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!
