$-\ln\left(\cos\left(x\right)\right)$
Learn how to solve problems step by step online. Solve the trigonometric integral int((sin(x)+cos(x))/(cos(x))dx. The integral \int\frac{\sin\left(x\right)}{\cos\left(x\right)}dx results in: -\ln\left(\cos\left(x\right)\right). The integral \int1dx results in: x. Gather the results of all integrals. As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration C.
