    I'm afraid that I do not agree with your interval for t.

    Among other things you have written
    [tex]\pi+ 2k\pi\le t\le 0+ 2k\pi[/tex]
    which implies that [itex]\pi[/itex] is negative!

    sin(t) is defined for ALL t. [itex]sin(\sqrt{x})[/itex] is defined as long as [itex]\sqrt{x}[/itex] is.
