Any ideas?

...Jim Thompson

Move one of the arctans to the other side of the equation, take the
tangent of both sides using the formula for tan(a+b), and solve it
algebraically.

Cheers

Phil Hobbs


The arctans are on the one side.

As I see it, applying TAN to both sides gives

TAN(THETA) = TAN(arctan1 + arctan2)

...Jim Thompson


There are different ways to do it, but you'll need the tan(a+b) formula.
That'll make it an algebraic equation rather than a transcendental one.

Cheers

A _messy_ Algebraic equation :-)

Oooops! I just realized the advantage of your approach... ding-dong
