Im afraid my use of LaTeX code, sucks. My apologies to anyone friendly enough to help!(adsbygoogle = window.adsbygoogle || []).push({});

The problem:

A string takes a path shown by the equation below:

r(t)=(t,3t^2,6t^3) Where the RHS is a verticle vector (didnt know how to code this!)

and 0 <= t <= 1

The mass per unit length of the wire at a point (x, y, z) is given by

p(x,y,z) = xyz^2

Im having trouble answering these last two questions..

c) Find the entire length of the string?

d) Find the mass of the string?

Thanks for your help!
