integral of x^2sqrt((11+x^3))

\int x^{2} (11 + x^{3}) d x

\frac{2}{9} (11 + x^{3})^{\frac{3}{2}} + C

Solution steps

\int x^{2} 11 + x^{3} d x

Apply u-substitution

: \int \frac{u}{3} d u

= \int \frac{u}{3} d u

Take the constant out:

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

= \frac{1}{3} \cdot \int u d u

Apply the Power Rule

: \frac{2}{3} u^{\frac{3}{2}}

= \frac{1}{3} \cdot \frac{2}{3} u^{\frac{3}{2}}

Substitute back

u = 11 + x^{3}

= \frac{1}{3} \cdot \frac{2}{3} (11 + x^{3})^{\frac{3}{2}}

Simplify

\frac{1}{3} \cdot \frac{2}{3} (11 + x^{3})^{\frac{3}{2}} : \frac{2}{9} (11 + x^{3})^{\frac{3}{2}}

= \frac{2}{9} (11 + x^{3})^{\frac{3}{2}}

Add a constant to the solution

= \frac{2}{9} (11 + x^{3})^{\frac{3}{2}} + C

\int_{5}^{6} 12 arccot (x) d x

(- 5, 3), (5, - 5)

\frac{d}{d x} (x cos (θ))

\int x y e^{- y x} d x
