Learn how to solve trigonometric integrals problems step by step online. Solve the trigonometric integral int((sin(x)+cos(x))/cos(x))dx. Expand the fraction \frac{\sin\left(x\right)+\cos\left(x\right)}{\cos\left(x\right)} into 2 simpler fractions with common denominator \cos\left(x\right). Simplify the resulting fractions. Expand the integral \int\left(\frac{\sin\left(x\right)}{\cos\left(x\right)}+1\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int\frac{\sin\left(x\right)}{\cos\left(x\right)}dx results in: -\ln\left(\cos\left(x\right)\right).

Final Answer

$-\ln\left(\cos\left(x\right)\right)+x+C_0$
