Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

sure! whichever method is easier for you! :)

@TheNumber2Pencil546 I'll definitely keep making them :)

What do you do in the case where you have a polynomial in the denominator and division by n^n makes all the terms = 0.

what if the function is something like (-1^n)((n^2)+n))/((4n^2)+1)
sorry for the ugly formatting, really helpful video! thanks!

I am also unsure about how to find the limit of sequence when the terms are raised to n. Could you maybe make a vid for that?
Example: n approaches infinity
(2^n)+1/(3^n)
Is there a method for this? :S

[jolupapi]

What if something is raised to the n???

[angeley]

Can't we just apply L'Hopital's rule instead of dividing by n^3?

very nice! keep making vids! it makes it also makes it easier to learn math when an attractive woman is teaching it as opposed to the old fart that i have as a professor

I hate to say this, but larry summers is wrong.
