$\int2\cos\left(x\right)dx$
Learn how to solve problems step by step online. Solve the trigonometric integral int(sin(2x)/sin(x))dx. Reduce \frac{\sin\left(2x\right)}{\sin\left(x\right)} by applying trigonometric identities. We can solve the integral \int2\cos\left(x\right)dx by applying the method Weierstrass substitution (also known as tangent half-angle substitution) which converts an integral of trigonometric functions into a rational function of t by setting the substitution. Hence. Substituting in the original integral we get.
