How to Integrate Complicated Volume Integrals of Spheres?

In summary, the formula for finding the volume of a sphere using integration is V = (4/3)πr^3, where r is the radius of the sphere and π is the mathematical constant pi. To set up the integral, we can use the formula V = ∫a^b A(x) dx, where a and b are the limits of integration and A(x) represents the cross-sectional area of the sphere at a given distance x from its center. Any method of integration can be used, but the most common approaches are the disk/washer method and the shell method. The radius of the sphere affects the integration process, as the limits of integration and the formula for the cross-sectional area will change accordingly. Volume integration

Assuming correctness up to the next to last line, you can look up the integral of (sinx)**3. The integral of sinx(cosx)**2 is like a**u du because you have du which is sinx * dx.
