my teacher says that when we do it we are only supposed to work on one side at a time so it isnt like solving an algebraec problem...thanks for all of the feedback though. much more than i expected

For your problems yes, I just used a simple identity, your questions are too tough for me to do in my head

, I will actually need a pencil and paper toevaluate them.

2cotX=csc(squared)XsinX
2+2cot(squared)X=2cotXsecXcscX
cotX/2sinX=1+cosX
2sinX-cscX=sinX-(cotX/secX)
1=cot(squared)X=2cotXcsc2X
sinXcosX=(cosX-cos(cubed)X/sinX)

what is your question? these are the basic trig identities.
