# Math Help - I am having trouble with this curvature problem

2. ## Re: I am having trouble with this curvature problem

You should have learned the formulas for curvature and length for a parametric curve in 3 dimensions. Start with that and plug in the values and let us know how far you get.

As for finding the curvature two ways, you should have learned two formulas - one involving the derivative of the tangent vector and the other involving a cross product.

Good luck,
