Find the integral. http://img83.imageshack.us/img83/1228/int203bd.gif [Broken] This one is just so confusing. *sigh* Find the antiderivative. http://img83.imageshack.us/img83/7179/int264ol.gif [Broken] I don't know how to approach this one.. I'm guessing making some substitutions.. but i don't know how you actually work it when you make subtitutions.. just like in my other post.. I can make substitutions.. but i don't know what to do after that. I need one with substitutions worked for me if they're all similar.
