integral of 1/(x^2sqrt(x^2-10))

\int \frac{1}{x ^{2} x ^{2} - 10} d x

\frac{x ^{2} - 10}{10 x} + C

Solution steps

\int \frac{1}{x ^{2} x ^{2} - 10} d x

Apply Trigonometric Substitution

: \int \frac{1}{10 sec ( u )} d u

= \int \frac{1}{10 sec ( u )} d u

Take the constant out:

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

= \frac{1}{10} \cdot \int \frac{1}{sec ( u )} d u

Rewrite using trig identities

= \frac{1}{10} \cdot \int cos (u) d u

Use the common integral:

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

= \frac{1}{10} sin (u)

Substitute back

u = arcsec (\frac{1}{10} x)

= \frac{1}{10} sin (arcsec (\frac{1}{10} x))

Simplify

\frac{1}{10} sin (arcsec (\frac{1}{10} x)) : \frac{x ^{2} - 10}{10 x}

= \frac{x ^{2} - 10}{10 x}

Add a constant to the solution

= \frac{x ^{2} - 10}{10 x} + C

\frac{s + 1}{( s + 6 ) ^{2} ( s + 2 )}

\frac{8}{3 x + 3}

f (x) = \frac{6 cos ( x )}{7 - 9 cos ( x )}

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

cos (2 x^{2})
