May 29, 2010 · The problem involves evaluating the integral \ (\int (x+2)dx/\sqrt {3+2x-x^2}\) using techniques such as completing the square and substitution. The subject area is calculus, specifically …

Dec 14, 2013 · Can someone explain to me how to solve this using inverse trig and trig sub? $$\int\frac {x^3} {\sqrt {1+x^2}}\, dx$$ Thank you.

Sep 22, 2020 · Is there a "nice" way to remember trigonometric integrals, beyond what is typically taught in a standard calculus class? I'm currently in Calculus II, and up to now I've found calculus rather …

Nov 26, 2015 · Nothing wrong with a trig sub, but you don't not HAVE to use a trig sub. Try a substitution $\sqrt {4-x^2}=t$ and see what happens

More to what you asked, any x outside the $\pm a$ range is complex, so having a trig substitution function that is "bounded" is totally appropriate. If you're doing complex integration, have bounds …

Also, sometimes integrals which one might normally approach with trig substitution are much quicker if one knows about explicit formulae for inverse hyperbolic trig functions. For example, $$ \int\frac {1} …
