integral from 1 to 2 of x^2(3/7 x^2)

\int_{1}^{2} x^{2} (\frac{3}{7} x^{2}) d x

\frac{93}{35}

Decimal Notation

2.65714 \dots

Solution steps

\int_{1}^{2} x^{2} \frac{3}{7} x^{2} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{3}{7} \cdot \int_{1}^{2} x^{2} x^{2} d x

Simplify

x^{2} x^{2} : x^{4}

= \frac{3}{7} \cdot \int_{1}^{2} x^{4} d x

Apply the Power Rule

: [\frac{x ^{5}}{5}]_{1}^{2}

= \frac{3}{7} [\frac{x ^{5}}{5}]_{1}^{2}

Compute the boundaries:

\frac{31}{5}

= \frac{3}{7} \cdot \frac{31}{5}

Simplify

= \frac{93}{35}

\int_{0}^{\frac{π}{2}} x^{3} \cdot cos (2 x) d x

\int_{1}^{4} 3 x^{2} + x x + 1 d x

\int_{- 1}^{1} \frac{1}{4} d x

\int_{1}^{5} sin (x^{2}) d x

\int_{0}^{1} 1 + cos (π x) d x
