$\int\frac{69}{82}x^2\cos\left(n\right)dx$

Learn how to solve integral calculus problems step by step online. Find the integral int(sin(1)xcos(n)x)dx. Simplify the expression inside the integral. The integral of a function times a constant (\frac{69}{82}) is equal to the constant times the integral of the function. The integral of a function times a constant (\cos\left(n\right)) is equal to the constant times the integral of the function. Apply the power rule for integration, \displaystyle\int x^n dx=\frac{x^{n+1}}{n+1}, where n represents a number or constant function, such as 2.
