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

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

- \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

\int \frac{x}{x} d x

\frac{1}{2} x^{3} + 2, x + 1, x = 0, x = 2

x \to 0 lim (+ (tan (7 x))^{x})

\frac{d}{d x} ((x^{4} + x^{2} + 1)^{4})

y = lo g_{2} (4 - 9 x)
