Thread: Find Mass of Rod?

A rod with constant cross section A and length L lies along the x-axis from x= 0 to x = L.
The density of the rod depends only on x and is given by rho(x) = e^(2x). Calculate the mass
of the rod.

Am I right doig this?


integral of A*e^(2x) dx = (A*(e^((2)(L)))/2-(e^((2)(0)))/2)

lots of ((( ))) to sift through, but I do believe you have the right idea ...
