The complex numbers z and w are graphed below. The quotient $$\dfrac{z}{w}$$ can be written in the form $$r(\cos\theta+i\sin\theta)$$ where $$r\geq 0$$ and  $$\theta\in[0,2\pi)$$. Find $$r\geq 0$$.

Since z = 2e^(i*pi//6) and w = 5e^(i*2*pi/3), z/w = 2/5e^(-5*pi/6).  Therefore, r = 2/5.

waits its supposed to be find $$(r,\theta)$$  not whetever it is above
