Derive the formula for the 4D volume of a hypersphere.
in 2D the area of a sphere is 4 * pi * r^2
in 3D the volume is just the integral of the area which is 4/3 * pi * r^3
so in 4D the "hypervolume" would be the integral again so it would be 1/3 * pi * r^4
waala, whats with these sequences, maybe the infinte sum of those equals to the equation just found.
