Hoo boy...

Um, yeah. I officially failed my calc final, or at least came out with a very low C. Like, I was all confident going in... and then I got the questions and blanked on everything. Like, I'm talking even basic math skills. So, in conclusion, I know the concepts, I just can't apply them. At all. Like... at all. If the ratio tests comes out to be less than 1, I know it converges. But the issue is getting it to come out to some sort of a number. P-series converges for p greater than 1, but there weren't any nice simple ones like that. At some point, I gave up and started making up math. I'm not even kidding. The following occured:   n  =      (n/n)      =     1     =   n   = n^2+1  (n^2)/n + (1/n)   n + (1/n)   n + 1        (n/n)    =     1    =   n   (n/n) + (1/n)  1 + (1/n)  1 + 1 Now, I'm fairly sure math doesn't actually work like that, at least, not the way I was trying to do it. ::sigh:: Oh well, retaking it during the summer will give me something to do.

its going from step 3 to step 4 that i don't get.

are you familiar with how the limit comparison works?

basically if the limit of the given series divided by a comparable series converge to a number other than zero, then they both converge or diverge.

You're an optimist :)


I don't tell many people this, but I failed Algebra. Twice. Both semesters. Which, actually, I redid one and came out with a B, but still. So my whole life was imaginary math for a while.
