Learn how to solve trigonometric integrals problems step by step online. Solve the trigonometric integral int(sec(x)/(3tan(x)+7))dx. Rewrite the trigonometric expression \frac{\sec\left(x\right)}{3\tan\left(x\right)+7} inside the integral. Simplify the expression inside the integral. We can solve the integral \int\frac{1}{3\sin\left(x\right)+7\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.
