SUMMARY
The integral of the function ∫ r^{3}√(r^{2}+1) dr can be effectively solved using a single u-substitution. By letting u = r^{2} + 1, the differential du = 2r dr simplifies the computation. This approach eliminates the need for trigonometric substitution, making the process more straightforward.
