    Formula for arctan(A*B) ?

    Is there a (sum?) formula for arctan(A*B)?

    I am trying to solve for x.

    Thanks!

    Forget the sum formula for your product. That doesn't make any sense.

    For your equation, two things:

    1) Are a and b related?
    2) How are your iterative methods?

    1) nope
    2) essentially non-existent
