I'll pay you 5 bucks if you can solve all of these for me. I'll send them via paypal or via address if you want. You have my word. Seriously.

tan?=1/sin?cos? - cos?/sin?

why would you start with the right side of the equation? can i get the proof too? thanks

can you prove these 4 equations as identities?

cscX - sinX transformed into cotX cosX

csc^2A+ cot^2A csc^2A=csc^4A

mmm thats it for now. solve them for me and you get 5 bucks!!
