integral from 2 to 5 of x^2+1/(x^2)

\int_{2}^{5} x^{2} + \frac{1}{x ^{2}} d x

\frac{393}{10}

Decimal Notation

39.3

Solution steps

\int_{2}^{5} x^{2} + \frac{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_{2}^{5} x^{2} d x + \int_{2}^{5} \frac{1}{x ^{2}} d x

\int_{2}^{5} x^{2} d x = 39

\int_{2}^{5} \frac{1}{x ^{2}} d x = \frac{3}{10}

= 39 + \frac{3}{10}

Simplify

39 + \frac{3}{10} : \frac{393}{10}

= \frac{393}{10}

\int_{2}^{4} (6 - x - y) d y

\int_{- 1}^{3} ∣ 2 x ∣ d x

\int_{0}^{\infty} e^{- 7 x^{2}} d x

\int_{0}^{2} (2 x + 2) d x

\int_{- 1}^{1} e^{y} sin (y) d y
