integral of x/((3-x)^2)

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

\frac{x}{3 - x} + ln ∣ 3 - x ∣ + C

Solution steps

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

Apply Integration By Parts

: \frac{x}{3 - x} - \int \frac{1}{3 - x} d x

= \frac{x}{3 - x} - \int \frac{1}{3 - x} d x

\int \frac{1}{3 - x} d x = - ln ∣ 3 - x ∣

= \frac{x}{3 - x} - (- ln ∣ 3 - x ∣)

Simplify

= \frac{x}{3 - x} + ln ∣ 3 - x ∣

Add a constant to the solution

= \frac{x}{3 - x} + ln ∣ 3 - x ∣ + C

\int cos^{4} (θ) sin (2 θ) d θ

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

\int sec^{2} (θ) sec (θ) d θ

\int \frac{( 16 x ^{3} )}{x ^{4} + 5} d x

\int sin (\frac{2 θ}{3}) d θ
