$${\int }_{\pi /2}^{\pi /4}(3x+7)$$

Answered by Joel577 last updated on 29/Sep/17

$$I=\underset{\frac{\pi }{2}}{\stackrel{\frac{\pi }{4}}{\int }}3x+7dx$$$$={[\frac{3}{2}{x}^2+7x]}_{\frac{\pi }{2}}^{\frac{\pi }{4}}$$$$=(\frac{3{\pi }^2}{32}+\frac{7\pi }{4})-(\frac{3{\pi }^2}{8}+\frac{7\pi }{2})$$$$=-(\frac{9{\pi }^2}{32}+\frac{7\pi }{4})$$
