Don't usually comment on videos but this series has been an absolute help! When my lecturer taught this boy, was I lost. This is absolutely amazing! Thank you !

Just quick question, why are we multiplying by the cosine of nt? Might be a daft question. Really good sequence of videos by the way-a pure labour of love!

[aaroncollins]

I keep seeing the average value expressed as 'a sub zero over two' but in this series you say it's just 'a sub zero'. Which one is correct?

what's the software u r using for writing?

[luisffp]

i have a question. why is he multiplying for cos(nt)? anyone knows? help, please!

Last video all these terms were 0. Strange how the laws of mathematics change between videos.

What the f*** is the point of these videos if you have no-where where you order them in the correct order, so we can watch them through?
