    As soon as you start involving infinite sets your mathematics is skating on thin ice.

    The ratio of all even positive integers and all positive integers is actually indeterminate, because we have "infinity/infinity" situation. It's just like we can't really know the answer unless we do more work(especially in calculus).

    f(x)=x*((1)/(x)) is always 1, but undefined when x reaches 0, if x -> 0, the limit is 0 by derivating f(x), which f'(x)=0

    May I ask Dr. Payne: I know all Taylor series are a power series, but is there a way you can help me understand why it’s true that every single power series is also a Taylor series? (Without heavy analysis as I never took an analysis course). Thanks so much! Would love to see a video on this if you would be so kind!

    I don't see this as something that needs someone's name put on and a lot of fancy attention - isn't this just what we've all been doing in our head when we solve these problems anyway? It's just common sense.
