InterviewSolution

1.	If ∫cos5x dx=nC0⋅sinx−nC1⋅sin3x3+nC2⋅sin5x5+C, then the value of (2n+3)C2 is equal to(where C is integration constant)
Answer» If $\int {cos}^{5} x d x =^{n} C_{0} \cdot sin x -^{n} C_{1} \cdot \frac{{sin}^{3} x}{3} +^{n} C_{2} \cdot \frac{{sin}^{5} x}{5} + C,$ then the value of $^{(2 n + 3)} C_{2}$ is equal to (where $C$ is integration constant)
