Homework Statement
Integrate some area C of (xe^y)ds where C is the arc of the curve x=e^y
Homework Equations
What is the indeffinite integral and why is it that? Answer is (1/3)e^3y + C
The Attempt at a Solution
Integral of (xe^y)((e^y)^2 + 1)^(1/2)
= Integral of (e^2y)(e^2y + 1)
= (e^3y)/3 + (e^2y)/2 + C
