It's a simple substitution . . .
I'm looking for help with what to do when you have a division over pi x.
I need to intergrate the following between 1 and 0
cos (pi x/2) dx
I'm fine with intergrating it as cos pi x. But I'm stuck with what to do when adding in the /2 under the pi x.
any help would be greatly appreciated! thanks!
1. There should be no integral sign as you've already done the integration.
2. There should be no since if you look at what I posted you ought to realise that in your case. The formula I gave you was a general case.
3. , so how can It doesn't.
