integral from 1 to 4 of 1/(x^3)+x

\int_{1}^{4} \frac{1}{x ^{3}} + x d x

\frac{255}{32}

Decimal Notation

7.96875

Solution steps

\int_{1}^{4} \frac{1}{x ^{3}} + x 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}^{4} \frac{1}{x ^{3}} d x + \int_{1}^{4} x d x

\int_{1}^{4} \frac{1}{x ^{3}} d x = \frac{15}{32}

\int_{1}^{4} x d x = \frac{15}{2}

= \frac{15}{32} + \frac{15}{2}

Simplify

\frac{15}{32} + \frac{15}{2} : \frac{255}{32}

= \frac{255}{32}

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

\int_{y^{2}}^{y} (x^{n} + y^{n}) d x

\int_{0}^{1} 10 x^{2} e^{x} d x

\int_{0}^{x} k x d x

\int_{0}^{π} x cos (2 x^{2}) d x
