(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Equation: [itex]\frac{z\theta_0^2}{-\theta^2+ 2i\theta\theta_0\phi+\theta_0^2}[/itex]

Where [itex]z, \ \phi[/itex] are constant and [itex]\theta_0[/itex] is the initial theta. Find the modulus and the phase associated with this equation.

2. Relevant equations

[itex]\frac{z\theta_0^2}{-\theta^2+ 2i\theta\theta_0\phi+\theta_0^2}[/itex]

3. The attempt at a solution

To find the modulus, I seperated the equation into real and imaginary and multiplied by the conjugate of the imaginary number to get it in the numerator and I got: [itex]=\frac{z\theta^2\phi - z\theta_0^2\phi}{\theta\phi} - \frac{z\theta_0}{2\theta\phi}i[/itex]. When doing the modulus, I get: [itex]\sqrt{\frac{4z^2\phi^2\theta^4-8\phi^2z^2\theta^2\theta_0^2+ 4z^2\theta_0^4\phi^2 +z^2\theta_0^2}{4\theta^2}\phi^2}[/itex] and this doesn't seem to simplify too well. Have I made a mistake or is there an easier method which I have missed? Thanks in advance for the help.
