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

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

- \frac{1}{x + 7} + C

Solution steps

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

Apply u-substitution

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

Apply the Power Rule

= - \frac{1}{u}

Substitute back

u = x + 7

= - \frac{1}{x + 7}

Add a constant to the solution

= - \frac{1}{x + 7} + C

\int - 8 sin (8 x) d x

y = 6 x + \frac{4}{3}

\int arccos (3 x) d x

\int (2 + x^{7})^{3} x^{6} d x

f (x) = 3 x^{3}
