I've never seen that inverse Tan identity. Cool.
Now you know
not to detract from the ingenuity of the solution, I do not understand the "dimensions" of the problem. The inverse of x is an angle in the numerator, but in the denominator it is the angle?
This confusion is because of the symbol used namely theta. Theta is dimensionless. Instead of theta we could have used for example x.
