What is the integral of (3x-7)^{11} ?

The integral of (3x-7)^{11} is 1/36 (3x-7)^{12}+C

integral of (3x-7)^{11}

\int (3 x - 7)^{11} d x

\frac{1}{36} (3 x - 7)^{12} + C

Solution steps

\int (3 x - 7)^{11} d x

Apply u-substitution

= \int \frac{u ^{11}}{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^{11} d u

Apply the Power Rule

= \frac{1}{3} \cdot \frac{u ^{12}}{12}

Substitute back

u = 3 x - 7

= \frac{1}{3} \cdot \frac{( 3 x - 7 ) ^{12}}{12}

Simplify

\frac{1}{3} \cdot \frac{( 3 x - 7 ) ^{12}}{12} : \frac{1}{36} (3 x - 7)^{12}

= \frac{1}{36} (3 x - 7)^{12}

Add a constant to the solution

= \frac{1}{36} (3 x - 7)^{12} + C

\int - 15 sec (- 3 x) tan (- 3 x) sec^{4} (- 3 x) d x

\int ((x^{2})^{2})^{2} d (x^{2})^{2}

\int \frac{8}{3 x ^{3} + 7 x ^{2} + 4 x} d x

\int sin (3 x) cos (4 x) cos (5 x) d x

\int 20 tan^{19} (x) sec^{2} (x) d x
