Question

Need help with this integral..

Answer 1

\[\int\limits_{}^{} (\sqrt{x^2-1})/(x) \]then i am stuck

Answer 2

well actually i get to \[\int\limits_{}^{}\tan^2\theta\]

Answer 3

use trig identity
tan^2 = sec^2 -1
\[\rightarrow \int\limits_{}^{}\sec^{2}\theta -1 = \tan \theta -\theta\]

Answer 4

remember to write +C as you need a constant lol
