Use this approach
Which way you integrate gives you the same answer, post the two answers, i'll show you how.
I have a query regarding a simple integration problem. See attached. It is regarding integrating (b-x)^2dx. The correct way is integrating this as a whole. At a first glance, I would have multiplied out the brackets and then integrated.....
Fantastic, I understand the original 'normalise psi question'. Its query I have regarding 2 ways of integrating (b-x)^2
1) using pickslides or ackbeets method which is fine or
2) my method of expanding out the brackets and integrating.
ok guys, I will look at it tomorrow. Its saturday night, I will mull it over my pint of guinneas!! :-)
I got myself in a twist because I came across the same problem in a different application. It turns out that if I correctly follow rules regarding the constants and limits the 3 methods work the same as you said. Thanks also to ackbeet and pickslides. See attached summary.
