F(x) = (4/5)*x^(5/4) on the interval of [0,4]
Find the Arc Length
Arc Length = Integral (sqrt (1 + [f(x)']^2)) dx
The Attempt at a Solution
F'(x) = x^(1/4)
Integral from [0,4] of Sqrt (1 + x^(1/2)) dx
I'm not sure where to go with this integral, I'm sure it's a substitution, however I've been at this all day and I have no idea what.
