$\int_{\frac{\pi}{6}}^{\frac{\pi}{2}}\sin\left(x\right)dx$
Learn how to solve definite integrals problems step by step online. Integrate the function sin(x) from pi/6 to pi/2. Simplifying. We can solve the integral \int\sin\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. Substituting in the original integral we get.
