Learn how to solve integral calculus problems step by step online. Find the integral int(-(sin(nx)/(n^2))dx. Take out the constant -1 from the integral. Take the constant \frac{1}{n^2} out of the integral. Multiplying the fraction by -1. We can solve the integral \int\sin\left(nx\right)dx by applying integration by substitution method (also called U-Substitution). First, we must identify a section within the integral with a new variable (let's call it u), which when substituted makes the integral easier. We see that nx it's a good candidate for substitution. Let's define a variable u and assign it to the choosen part.

Final Answer

$\frac{\cos\left(nx\right)}{n^{3}}+C_0$
