$3\int\cos\left(x^2\right)dx$
Learn how to solve trigonometric integrals problems step by step online. Solve the trigonometric integral int(3cos(x^2))dx. The integral of a function times a constant (3) is equal to the constant times the integral of the function. Rewrite the function \cos\left(x^2\right) as it's representation in Maclaurin series expansion. Simplify \left(x^2\right)^{2n} using the power of a power property: \left(a^m\right)^n=a^{m\cdot n}. In the expression, m equals 2 and n equals 2n. We can rewrite the power series as the following.
