Polar to Cartesian form.

[Crush.]

Need help converting from polar form to cartesian form.

4^1/8[cos(11pi/32)+isin(11pi/32)]

Show the steps of how to do it if possible.

Thanks

Is that a command or a request for help?
Actually \(\displaystyle \frac{11\pi}{32}\) is not one of the nice measures.
So there is no neat(exact) solution.

What, exactly, is the problem? Do know how to find \(\displaystyle 4^{1/8}= 2^{2/8}= 2^{1/4}\)? Do you know how to find cos(11pi/32) or sin(11pi/32)? Use a calculator for both.
