    Undergrad What is the Curvature of a Helix Given by a Parametric Equation?

    Homework Statement Find the curvature of a helix given by the parametric equation r(t)=<acost, asint, bt> where a and b are real numbers Homework Equations I know k=|T'(t)/r'(t)| The Attempt at a Solution and I believe the answer to be k=b/(a2+b2)1/2, I just don't know how to get there
