integral of 3x^2(x^3+1)^{10}

\int 3 x^{2} (x^{3} + 1)^{10} d x

\frac{1}{11} (x^{3} + 1)^{11} + C

Solution steps

\int 3 x^{2} (x^{3} + 1)^{10} d x

Take the constant out:

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

= 3 \cdot \int x^{2} (x^{3} + 1)^{10} d x

Apply u-substitution

: \int \frac{u ^{10}}{3} d u

= 3 \cdot \int \frac{u ^{10}}{3} d u

Take the constant out:

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

= 3 \cdot \frac{1}{3} \cdot \int u^{10} d u

Apply the Power Rule

: \frac{u ^{11}}{11}

= 3 \cdot \frac{1}{3} \cdot \frac{u ^{11}}{11}

Substitute back

u = x^{3} + 1

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

Simplify

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

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

Add a constant to the solution

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

x \to 4 lim (9 - x - 5)

\frac{\partial}{\partial x} (1 + x^{2})

x \to 2 π lim (ln (cos (x)))

4 x sin (x)

\int \frac{1}{sec ( 2 x )} d x
