integral of 8/(1-x^2)

\int \frac{8}{1 - x ^{2}} d x

8 (\frac{ln ∣ x + 1 ∣}{2} - \frac{ln ∣ x - 1 ∣}{2}) + C

Solution steps

\int \frac{8}{1 - x ^{2}} d x

Take the constant out:

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

= 8 \cdot \int \frac{1}{1 - x ^{2}} d x

Use the common integral:

\int \frac{1}{1 - x ^{2}} d x = \frac{ln ∣ x + 1 ∣}{2} - \frac{ln ∣ x - 1 ∣}{2}

= 8 (\frac{ln ∣ x + 1 ∣}{2} - \frac{ln ∣ x - 1 ∣}{2})

Add a constant to the solution

= 8 (\frac{ln ∣ x + 1 ∣}{2} - \frac{ln ∣ x - 1 ∣}{2}) + C

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

\int 4 x 3 3 x^{2} + 2 d x

\int \frac{x ^{2} + 1}{x ^{2} + 4} d x

\int \frac{- 1}{x + 2} d x

\int π t d t
