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

integral

\frac{x ^{2} - 1}{x ^{2}}

- \frac{x ^{2} - 1}{x} + ln x^{2} - 1 + x + C

Solution steps

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

Apply Integration By Parts

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

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

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

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

Simplify

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

Add a constant to the solution

= - \frac{x ^{2} - 1}{x} + ln x^{2} - 1 + x + C

(x - 1) e^{x}

f (x) = arctan (x^{\frac{1}{2}})

(x + 2)^{n}

\frac{sin ^{4} ( x )}{cos ( x )}

(cos^{2} (x))^{2}
