Fixed typo in the result. Apr12 revised Integral of $\cot^2 x$? Added (trigonometry) tag Apr12 comment Troubles with this $\int{\sqrt{x^2-2x-1}}dx$ I would use the adequate Euler substitution math.stackexchange.com/search?q=user%3A752+euler+substitution . Alternatively complete the square and use a trigonometric substitution.
