$\int_{0}^{\frac{\pi}{3}}-\sin\left(x\right)dx$

Learn how to solve definite integrals problems step by step online. Integrate the function -sin(x) from 0 to pi/3. Simplifying. The integral of a constant times a function is equal to the constant multiplied by the integral of the function. Apply the integral of the sine function: \int\sin(x)dx=-\cos(x). Evaluate the definite integral.
