    help with composite function for trig

    So the question is which is greater? Cos(sinx) or Sin(cosx)? i could prove this by graphing but i kinda need algebraically. Any help would be greatly appreciated.

    Neither function is ever always greater then the other.

    oh okay. yea that does make sense. I can analyze and prove that graphically. however, it says that i have to also prove this algebraically as well. So would you know how to do this?
