Follow-up Question
In the last step of the solution you have 2sqrt(5)/(sqrt(5))2. Isn't that supposed to be 2sqrt(5)/(sqrt(5))3? It is cubed in the original equation for curvature so was wondering if that was just a typo in the solution or if there is a reason the denominator is squared instead of cubed?
