Hyperbolic substitution edit
Anyone care to start an article on hyperbolic substitution ? 71.182.215.210 12:56, 7 November 2007 (UTC)
Broken link edit
The link in the section that reads "Example (see quintic of l'Hôspital):" is broken. --24.207.236.232 (talk) 23:31, 28 November 2007 (UTC)
Cubic secant integral edit
I think there is an easier way to do the trig substitution of the form sqrt(x^2-a^2) that doesn't leave you in the pit of integrating sec^3(x). I will look into it and update this page accordingly (assuming I can find sources). 134.114.108.56 (talk) 15:18, 5 May 2008 (UTC)
One of the formulas has been changed edit
Someone edited one of the formulas in this article last month, replacing a division with a multiplication. Is this new formula incorrect? Jarble (talk) 05:47, 17 December 2017 (UTC)
alternative substitution edit
Someone may want to try to integrate these alternative substitutions which apparently work in all of the cases introductory calculus students are traditionally taught to use trigonometric substitutions, but with less new things for students to memorize:
