Find the arc length in the second quadrant of the curve
x^(2/3) + y^(2/3) = 4 from x = -8 to x = -1.
Ok what I'm thinking i should do is:
y^(2/3) = 4 - x^(2/3)
But here's where I get stuck.
I'm thinking I should ^(1/6) both sides, but that gets really ugly. It seems to me there should be an easier way to set this up.
