Hello,
I still get a little bit muddled whenever transferring angles from one quadrant to another. I was wondering if anybody knew any resource/tutorial that teaches you how to do this, preferably in radians? I've been trying to look this up, but I always come across tutorials that are in degrees.
Any help would be much appreciated!
Thank you,
Gina
it's all about understanding how a calculator determines the value of inverse trig functions.
say you have and x is in quadrant II ...
because the calculator calculates the value of as a positive quad I angle.
say you have and x is in quad III ...
because the calculator calculates as a negative angle in quad IV.

you should be able to generalize the above examples.
