Im afraid my use of LaTeX code, sucks. My apologies to anyone friendly enough to help! 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!
