$\int\left(\sin\left(x\right)^4-\cos\left(x\right)^4\right)dx$
Learn how to solve problems step by step online. Integrate the function sin(x)^4-cos(x)^4. Find the integral. Expand the integral \int\left(\sin\left(x\right)^4-\cos\left(x\right)^4\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int\sin\left(x\right)^4dx results in: \frac{-\sin\left(x\right)^{3}\cos\left(x\right)}{4}+\frac{3}{4}\left(\frac{x}{2}-\frac{1}{4}\sin\left(2x\right)\right). Gather the results of all integrals.
