integral of 1/(xsqrt(12x^2-3))

\int \frac{1}{x 12 x ^{2} - 3} d x

\frac{1}{3} arcsec (2 x) + C

Solution steps

\int \frac{1}{x 12 x ^{2} - 3} d x

Apply Trigonometric Substitution

= \int \frac{1}{3} d u

Take the constant out:

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

= \frac{1}{3} \cdot \int 1 d u

Integral of a constant:

\int a d x = a x

= \frac{1}{3} \cdot 1 \cdot u

Substitute back

u = arcsec (\frac{2 3}{3} x)

= \frac{1}{3} \cdot 1 \cdot arcsec (\frac{2 3}{3} x)

Simplify

\frac{1}{3} \cdot 1 \cdot arcsec (\frac{2 3}{3} x) : \frac{1}{3} arcsec (2 x)

= \frac{1}{3} arcsec (2 x)

Add a constant to the solution

= \frac{1}{3} arcsec (2 x) + C
