integral of 1/((1+x)^{7/2)}

\int \frac{1}{( 1 + x ) ^{\frac{7}{2}}} d x

- \frac{2}{5 ( 1 + x ) ^{\frac{5}{2}}} + C

Solution steps

\int \frac{1}{( 1 + x ) ^{\frac{7}{2}}} d x

Apply u-substitution

: \int \frac{1}{u ^{\frac{7}{2}}} d u

= \int \frac{1}{u ^{\frac{7}{2}}} d u

Apply the Power Rule

: - \frac{2}{5 u ^{\frac{5}{2}}}

= - \frac{2}{5 u ^{\frac{5}{2}}}

Substitute back

u = 1 + x

= - \frac{2}{5 ( 1 + x ) ^{\frac{5}{2}}}

Add a constant to the solution

= - \frac{2}{5 ( 1 + x ) ^{\frac{5}{2}}} + C

\int (3 x^{2} - 8 x) e^{2 x} d x

\int \frac{x}{4 x - 1} d x

\int cos^{1} (x) sin^{5} (x) d x

\int - sec^{2} (\frac{9 x}{7}) d x

\int \frac{2 cos ( x )}{1 + 4 sin ^{2} ( x )} d x
