1. The problem statement, all variables and given/known data So I'm trying to find the integral of P = 2xyz^2 along the curve c which is defined by: x=t^2 y=2t z=t^3 t goes from 0 to 1 So the q says that it is the integral of P dr along c 2. Relevant equations 3. The attempt at a solution So I know that this should equal the integral of P times mod r'(t) dt.. But if r = (t^2, 2t, t^3) then mod of r'(t) is pretty ugly..and I can't solve the integral.. Any pointers?
