## Trigonometry 7th Edition

To divide two complex numbers in trigonometric form, $divide$ their moduli and $subtract$ their arguments.
To divide two complex numbers in trigonometric form, $divide$ their moduli and $subtract$ their arguments. If $z_{1}=r_{1}cis\theta_{1}$, $z_{2}=r_{2}cis\theta_{2}$, then, $\frac{z_{1}}{z_{2}}=\frac{r_{1}}{r_{2}}cis(\theta_{1}-\theta_{2})$
