    i think you wrote it wrong. it should be
    [tex]\sin^{2}t = \left(\frac{1}{\cosh p}\right)^2[/tex]

    What is the actual question you are asking here? Are you asking why, or if, the left implies the right. Have you done anything to attempt to show this? I doubt anyone will help unless you firstly specify your question, and secondly show some effort!
