I know the answer to this question but am having a hard time understanding a few things. Arrange in order from least to greatest. arctan(-9) ; arccos1(-.22) arcsin(-1) arc sin1(0.84) arccos(1) why is arcsin(-1) -pi/2? how did we get arccos(.22) is in q2? Will you explain this problem im really not getting it.
I haven't seen that stuffs since I dropped out of differential equations :s
