integral of (1-2x)^9

\int (1 - 2 x)^{9} d x

- \frac{1}{20} (1 - 2 x)^{10} + C

Solution steps

\int (1 - 2 x)^{9} d x

Apply u-substitution

: \int - \frac{u ^{9}}{2} d u

= \int - \frac{u ^{9}}{2} d u

Take the constant out:

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

= - \frac{1}{2} \cdot \int u^{9} d u

Apply the Power Rule

: \frac{u ^{10}}{10}

= - \frac{1}{2} \cdot \frac{u ^{10}}{10}

Substitute back

u = 1 - 2 x

= - \frac{1}{2} \cdot \frac{( 1 - 2 x ) ^{10}}{10}

Simplify

- \frac{1}{2} \cdot \frac{( 1 - 2 x ) ^{10}}{10} : - \frac{1}{20} (1 - 2 x)^{10}

= - \frac{1}{20} (1 - 2 x)^{10}

Add a constant to the solution

= - \frac{1}{20} (1 - 2 x)^{10} + C

e^{t} \cdot cos (2 t)

\int_{0}^{2} t^{3} (3 + t^{4})^{3} d t

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

f (x) = 2 - x

\int \frac{( x + 1 )}{x ^{2} ( x - 1 )} d x
