Hello all,
We've just begun integration in my maths class and I have a question about a certain aspect of integration by substitution.
Let's say for instance you let u = 2x-1. Then you differentiate it and get du/dx = 2.
My maths teacher said " you can now think of it as multiplying across by 'dx' ".
Which leads to du = 2dx.
My question is, what mathematical operations are you actually committing to achieve this line?
Thanks in advance for any help.
