integral from 3 to 9 of (1+x^2)

Solution

\int_{3}^{9} (1 + x^{2}) d x

Solution

240

Solution steps

\int_{3}^{9} 1 + x^{2} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{3}^{9} 1 d x + \int_{3}^{9} x^{2} d x

\int_{3}^{9} 1 d x = 6

\int_{3}^{9} x^{2} d x = 234

= 6 + 234

Simplify

= 240
