Classes start back up for me Monday and I am taking Calculus II so I thought I should brush up a bit at the Khan Academy mentioned in another thread.
A bit of background; I returned to school a couple of semesters ago after a lengthy (over ten years) break. I just barely failed Calculus II last semester at another university. This was partially due to the gap, but also due to an abysmal performance by the faculty. For that reason (among others) I changed schools.
Anyway, I find it amazing that substitution and integration-by-parts are simply methods for reversing the chain and product rules respectively. This was never pointed out in my previous course and perhaps they simply expected us to make the connection ourselves. Whatever the case, we screamed through this stuff and I never really understood the why's to what we were doing. Personally, I find I can remember and apply what I have learned much more effectively when I understand why I am doing something. Perhaps that is a flaw, but there it is.
Anyway, this is an unabashed plug for these youtube videos. For whatever reason, I really feel like I understand this guy better than just about any professor I have ever had. If you are struggling with something math related, I highly recommend you check this guy out.
Best Regards,
Mark
