Learn how to solve trigonometric integrals problems step by step online. Solve the trigonometric integral int(sin(y)/(cos(y)^2))dy. Simplify \frac{\sin\left(y\right)}{\cos\left(y\right)^2} into \tan\left(y\right)\sec\left(y\right) by applying trigonometric identities. Apply the formula: \int\sec\left(\theta \right)\tan\left(\theta \right)dx=\sec\left(\theta \right)+C, where x=y. As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration C.
