Converting Polar to Cartesian - Step by Step Guide

[chap]

I'm back studying after a couple of years out and have become a little rusty. currently learning about the J operator.

I have no problem converting Cartesian to Polar, but struggle to convert Polar to Cartesian. Some basic examples and a step by step guide would be appreciated.


Thank you in advance.

Given (r,\theta ) you can get (x,y) by the following procedure:

x=r\cos(\theta)
y=r\sin(\theta)

Simple now you've pointed it out.

Thanks, that helps a lot.

Easier than cartesian to polar, huh?

I know, I was thinking the same thing.
