integral of (sqrt(2x^2-16))/(3x)

\int \frac{2 x ^{2} - 16}{3 x} d x

\frac{1}{3} (2 x^{2} - 16 - 4 arctan (\frac{1}{4} 2 x^{2} - 16)) + C

Solution steps

\int \frac{2 x ^{2} - 16}{3 x} d x

Take the constant out:

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

= \frac{1}{3} \cdot \int \frac{2 x ^{2} - 16}{x} d x

Apply Integration By Parts

: 2 x^{2} - 16 - \int \frac{16}{x 2 x ^{2} - 16} d x

= \frac{1}{3} (2 x^{2} - 16 - \int \frac{16}{x 2 x ^{2} - 16} d x)

\int \frac{16}{x 2 x ^{2} - 16} d x = 4 arctan (\frac{1}{4} 2 x^{2} - 16)

= \frac{1}{3} (2 x^{2} - 16 - 4 arctan (\frac{1}{4} 2 x^{2} - 16))

Add a constant to the solution

= \frac{1}{3} (2 x^{2} - 16 - 4 arctan (\frac{1}{4} 2 x^{2} - 16)) + C

\int \frac{x ^{7}}{x ^{8} + 1} d x

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

\int 2 + sin (t) d t

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

\int e^{\frac{x}{a}} + e^{- \frac{x}{a}} d x
