# Thread: Formula for arctan(A*B) ?

1. ## Formula for arctan(A*B) ?

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

I am trying to solve for x.

Thanks!

2. 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
