$\int\left(\frac{r^2}{100}+\frac{-t^2}{49}\right)dt$
Learn how to solve problems step by step online. Find the integral of (r^2)/100+(-t^2)/49. Find the integral. Expand the integral \int\left(\frac{r^2}{100}+\frac{-t^2}{49}\right)dt into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int\frac{r^2}{100}dt results in: \frac{1}{300}r^{3}. The integral \int\frac{-t^2}{49}dt results in: -\frac{1}{147}t^{3}.
