Final answer to the problem
Step-by-step Solution
Learn how to solve trigonometric integrals problems step by step online. Solve the trigonometric integral int(sin(-x))dx. Use the odd-even identity \sin(-\theta)=-\sin(\theta). The integral of a function times a constant (-1) is equal to the constant times the integral of the function. Apply the integral of the sine function: \int\sin(x)dx=-\cos(x). Any expression multiplied by 1 is equal to itself.
