I would appreciate it so much if someone could help me with these! I need the method and the answer, because the way I'm doing it seems to be all wrong.. I am not even sure I know what I'm doing.. So I need someone to explain it to me.. THANK YOU so much!
Use identities to obtain approximate solutions to these equations giving all answers to the nearest degree:
1) 3cos^2 x - sin x - 2 = 0, 0 _< x _< 360 degrees
2) 2cos^2x + 3 sin x = 3, 0 _< x _< 180 degrees
thank you so much!
