Write the complex number in rectangular form. 3cis52degrees ( round to 3 decimal places)
Yes, that's right, now just use your calculator to approximate the rectangular components. Rectangular form is:
$\displaystyle a+bi$ where $\displaystyle a,b\in\mathbb{R}$ (i.e. $\displaystyle a$ and $\displaystyle b$ are real.)
Here we have:
$\displaystyle a=3\cos\left(52^{\circ} \right)$
$\displaystyle b=3\sin\left(52^{\circ} \right)$
