    I doubt this is how the original question is written. Go back, check then post it exactly as it's originally written.

    *sigh* I really thought you'd re-post something like \tan (\cot^{-1} x - \cos^{-1} x) = ? ...... But far be it for me to doubt you or your textbook.

    Unfortunately, the question as you've posted it makes no mathematical sense. As such, it's undoable.
