$\int2\cos\left(x\right)dx$
Learn how to solve trigonometric integrals problems step by step online. Solve the trigonometric integral int(sin(2x)/sin(x))dx. Simplify \frac{\sin\left(2x\right)}{\sin\left(x\right)} into 2\cos\left(x\right) by applying trigonometric identities. The integral of a function times a constant (2) is equal to the constant times the integral of the function. Apply the integral of the cosine function: \int\cos(x)dx=\sin(x). As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration C.
