## Homework Statement

Find the arclength of the section y=x

^{2}between points (-2,2) and (2,4)

## Homework Equations

L = [tex]\int\sqrt{(\frac{dx}{dt})^2+(\frac{dy}{dt})^2}[/tex]

## The Attempt at a Solution

So what I did first is find the derivative of y=x

^{2}which is y

^{'}=2x

So I put that into the formula and get [tex]\int\sqrt{1+4x^2}[/tex] from limit point 1 to 4

From this point on I attempted to do u-substitution but it didn;t seem to work.. Anyone have any suggestions o how I can get it done?
