Find the path length of y= (x^3)/(a^2) + (a^2)/(12x)
I know I'm supposed to be integrating ds = dx (1+ (dy/dx)^2)^1/2
but i'm having trouble simplifying the expression inside the square root..
thanks in advance!

so the derivative is
that means you should then evaluate the integral

Reason: Made brackets large
