1. How do you use the trigonometic quantant to find the solutions in the range of -180<0<180 degrees :/

I believe it is best for u to sketch a graph and use the symmetry to work out all the values in that range.

Ohh cant it be done using the quadrant thing? :/

4. Draw the angle relative to the x axis. See how many solutions there are in the given range. I'm sorry if this is vague but I can't really explain this over text.

Try drawing a graph too.

It can but most people find using graphs much easier.
