(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the curvature of a helix given by the parametric equation r(t)=<acost, asint, bt> where a and b are real numbers

2. Relevant equations

I know k=|T'(t)/r'(t)|

3. The attempt at a solution

and I believe the answer to be k=b/(a^{2}+b^{2})^{1/2}, I just don't know how to get there
