Express the limit as a definite integral on the given interval. \[ \begin{array}{c} \lim _{n \rightarrow \infty} \sum_{i=1}^{n} \frac{\cos \left(x_{i}\right)}{x_{i}} \Delta x,[2 \pi, 3 \pi] \\ \int_{2 \pi}^{3 \pi}\left(\square \frac{}{2}\right) d x \end{array} \] \( -/ 1 \) Points] SCALCET9 5.2.026. Express the integral as a limit of Riemann sums using right endpoints. Do not evaluate the limit. \[ \begin{array}{r} \int_{5}^{8}\left(x^{2}+\frac{1}{x}\right) d x \\ \lim _{n \rightarrow \infty} \sum_{i=1}^{n}( \end{array} \]
