Learn how to solve problems step by step online. Solve the trigonometric integral int(sin(x)/cos(x))dx. Simplify \frac{\sin\left(x\right)}{\cos\left(x\right)} into \tan\left(x\right) by applying trigonometric identities. The integral of the tangent function is given by the following formula, \displaystyle\int\tan(x)dx=-\ln(\cos(x)). As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration C.
