I have to rewrite the following to polar form: re^iθ (θ is in radian).
I think that I have to use this: r*cos(θ) + i * sin(θ)
Please help!
I think it is
$$\\2e^{i\pi/6}\\\\
=2(cos\frac{\pi}{6}+isin\frac{\pi}{6})\\\\
=2(\frac{\sqrt3}{2}+i*\frac{1}{2})\\\\
=\sqrt3+i$$
-----------------
You do not need this pic to answer the question but I think it may help you to understand
Thanks for the help.
I just dont understand why you use π/6?
How do you know that θ = π/6?
