#90762 integration by substitution

Posted by Hev on 06 November 2006 - 10:21 PM in Mathematics

ok i've got it now, thanks smile.gif i pritty much got the most of it, except where u changed the limits? i'm not sure if we actually did those in class, i don't have them in my notes, but i miss out 40 minutes a week due to a double period class with advanced higher biology classes so i might just have missed it out in class. i'll go back and try n learn that better. calculus is not my favourite i must say. but thank you for all your help



#90759 integration by substitution

Posted by Hev on 06 November 2006 - 10:03 PM in Mathematics

ok, so when u have the d[theta] that means times by d[theta] so u change it for dx/cos[theta]?

we have two teachers for the advanced course, and one of them i understand but the other i don't follow her style of teaching atall, n it's her that's teaching us this.

using the substituion x= 1 + sin[theta] evaluate

integral of cos[theta] over (1+sin[theta])^3 with respect to theta

which is defined by pie/2 and 0

anyone help me?
