After substituting my data into the equation I can't simplify it far enough to take the integral
1. Find the surface area generated by rotating the curve about the y-axis
2. X=(1/3)Y^(3/2)-Y^(1/2) between 1 and 3
3. x' = (1/2)Y^(1/2) - (1/2)Y^(-1/2)
x'^2 = (y^2-2y+1)/4y
I'm not sure if that derivative is correct or if implicit differentiation is required. I also can't get any...
