SUMMARY
The integral of sin(101x) sin^99(x) dx can be solved using complex number representations and trigonometric identities. The transformation of sin(101x) into its exponential form, \(\frac{e^{101ix}-e^{-101ix}}{2i}\), along with the identity for sin^99(x) as Im(e^{99ix}), provides a pathway to the solution. Utilizing reduction formulas and trigonometric identities, the integral simplifies to a sum of cosine functions, leading to a final expression involving multiple cosine terms.
