Could you explain how you did the integral to check the answer?
The TI-Nspire CAS has a built-in function for finding the magnitude of a vector, it's called norm(). So I found the derivative of the vector valued function, then found its norm, then integrated that. (This is probably not a good explanation...!)
@@turksvids yeah I have the CAS, and I have an answer to a similar question but I don't know if it's right...
