We are using "HL Maths for the IB Diploma"We have equations like the first one you showed, maybe more complicated. I was wondering. When you have found the two solutions to an equations, and now need to find the rest withing the domain like 0

I have a math test on this tomorrow..or technically today. Down side: We dont get to use a unit circle or anything on the test so we have to memorize. In the other hand i have the memorized the sin/cos/tan table from 0-210 degrees. Well Im gonna check back with you later. Good job btw
