x^2=9y^3

from point A to point B, where

A=(0,0) and B=(81,9)

Please help, I have no clue as to where to go with this problem! Thanks!

We have a formula for the length of an arc,

I assume you have that.

If not look here

You will have to find dy/dx of your equation, then square it, add one , take the square root and then integrate that !!!
