Resources: Final Exam review problem 12


This problem requires you to find the values of trig functions given the value of one of them, plus information about the quadrant. You may need to review: the coordinate plane definitions of the trig functions; the signs of the trig functions in the four quadrants. (People insist on using a mnemonic for that, but it’s really not necessary: think about the unit circle.)
