1.	Let In=∫sinnx dx and Jm=∫cosmx dx. If I4+J4=Ax+Bsin4x+C, then AB is equal to(where C is integration constant)
Answer» Let $I_{n} = \int {sin}^{n} x d x$ and $J_{m} = \int {cos}^{m} x d x .$ If $I_{4} + J_{4} = A x + B sin 4 x + C,$ then $\frac{A}{B}$ is equal to (where $C$ is integration constant)
