## Homework Statement

Calculate the arc length of [itex]<2t,t^2,lnt>[/itex] from [itex]1=<t=<e[/itex]

## Homework Equations

Arc length=[itex]∫√{(x')^2 + (y')^2 + (z')^2}[/itex]

## The Attempt at a Solution

So I have gotten to this point:

[itex]∫√{4 + 4t^2 + \frac{1}{t^2}}[/itex]

Am I on the right track, and if so, how do I integrate that?
