integral from 1 to 2 of (2x^3+6/(x^2))

\int_{1}^{2} (2 x^{3} + \frac{6}{x ^{2}}) d x

\frac{21}{2}

Decimal

10.5

Solution steps

\int_{1}^{2} 2 x^{3} + \frac{6}{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_{1}^{2} 2 x^{3} d x + \int_{1}^{2} \frac{6}{x ^{2}} d x

\int_{1}^{2} 2 x^{3} d x = \frac{15}{2}

\int_{1}^{2} \frac{6}{x ^{2}} d x = 3

= \frac{15}{2} + 3

Simplify

\frac{15}{2} + 3 : \frac{21}{2}

= \frac{21}{2}

\int_{a}^{\infty} \frac{1}{x ^{2} + 1} d x

\int_{0}^{25} 4 x d x

\int_{- \frac{1}{2}}^{\frac{1}{2}} (x^{3} - 4 x) d x

\int_{0}^{3} 1 + (2 x)^{2} d x

\int_{2}^{5} 2 x^{2} - cos (2 x) d x
