integral from 1 to 5 of (sqrt(x^2-1))/x

\int_{1}^{5} \frac{x ^{2} - 1}{x} d x

- arctan (26) + 26

Solution steps

\int_{1}^{5} \frac{x ^{2} - 1}{x} d x

Apply u-substitution

: \int_{0}^{26} \frac{u ^{2}}{u ^{2} + 1} d u

= \int_{0}^{26} \frac{u ^{2}}{u ^{2} + 1} d u

\frac{u ^{2}}{u ^{2} + 1} = - \frac{1}{u ^{2} + 1} + 1

= \int_{0}^{26} - \frac{1}{u ^{2} + 1} + 1 d u

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= - \int_{0}^{26} \frac{1}{u ^{2} + 1} d u + \int_{0}^{26} 1 d u

\int_{0}^{26} \frac{1}{u ^{2} + 1} d u = arctan (26)

\int_{0}^{26} 1 d u = 26

= - arctan (26) + 26

\int 9 sin^{2} (θ) d θ

\frac{2 - x ^{2}}{( 2 + x ^{2} ) ^{2}}

\frac{d}{d x} (4 x^{3} ln (x))

f (x) = 110 x - 16 x^{2}, at x = 3.438

\int 6 cos (7 x) d x
