## Homework Statement

Determine the arc length of the function on the given interval

x = (y^4)/8 + 1/(4y^2) from 1 to 2

The arc length formula

[itex]\int[/itex] (f'(x)

^{2}+ 1)

^{.5}dx

## The Attempt at a Solution

I used the arc length formula but don't know where to go from here. Usually these problems can't be done unless a form of cancellation takes place and I can't seem to find it. Below is what I input in the formula but I can not figure out how to integrate this.

[itex]\int[/itex]((y

^{6}- 1)

^{2}/(2y

^{3})) + 1)))

^{.5}dy
