integral of 1/(x^2sqrt(x^2-6))

\int \frac{1}{x ^{2} x ^{2} - 6} d x

\frac{x ^{2} - 6}{6 x} + C

Solution steps

\int \frac{1}{x ^{2} x ^{2} - 6} d x

Apply Trigonometric Substitution

: \int \frac{1}{6 sec ( u )} d u

= \int \frac{1}{6 sec ( u )} d u

Take the constant out:

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

= \frac{1}{6} \cdot \int \frac{1}{sec ( u )} d u

Rewrite using trig identities

= \frac{1}{6} \cdot \int cos (u) d u

Use the common integral:

\int cos (u) d u = sin (u)

= \frac{1}{6} sin (u)

Substitute back

u = arcsec (\frac{1}{6} x)

= \frac{1}{6} sin (arcsec (\frac{1}{6} x))

Simplify

\frac{1}{6} sin (arcsec (\frac{1}{6} x)) : \frac{x ^{2} - 6}{6 x}

= \frac{x ^{2} - 6}{6 x}

Add a constant to the solution

= \frac{x ^{2} - 6}{6 x} + C

\int_{0}^{3} (2 e^{x}) d x

f (x) = \frac{x + 2}{10 - 3 x}

\int_{5}^{7} x^{3} d x

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

\int_{0}^{3} 3 x^{2} d x
