sqrt(x) = x^2  x^4 0 = x^2 sqrt(x) x^4 that does seem a bit convoluted :/

I'd: Write y as function of x: y=xsqrt(1x²) Integrate using u=1x² Multiply by 4, because of the symmetry...

what do I multiply by 4?

If you integrate as I did, you only get the area between the positive xaxis and the graph (upper right part of the whole thing) There a 4 such areas, so multiply by 4.
