Infinite is not a number......
-
how come we dont use the quotient rule when deriving
-
Is L'Hopital rule allowed in High-school tests?
-
so the first example using an infinity is just an indeterminate form and variation of the 0/0 form for l'hopitals rules right?
-
When doing limits at infinity, you can also just look at the leading coefficients. In this problem, they are 4x^2 and 3x^2. The x^2 cancels on both the top and the bottom and you're left with -4/3.

I'm gonna get an F

hi do u have gf i luv u

ขอบคุณมากครับมีแปลไทยด้ย thanks a lot. have translate it is very good.
thank you very much -
Good explanation !!
-
i'm confused... I mean it makes total sense that it would be +infinity over -infinity
but
it would also make sense that it should be4/3 since the 5x wouldn't matter as x>inf. and the 1 in the denominator shouldn't matter as compared to the -3x^2
when is that latter proposition the case instead of +inf/-inf? I know that it's also a very common thing
edit:
lol, just noticed that that's exactly the answer that we got as the video proceeded. I guess I was just thinking about a shortcut -
as always, good stuff
-
So you derived (4x^2-5x)/(1-3x^2) and then did it another time to get -4/3?
I thought it was f'(x)/g'(x) = L but in this case it was f''(x)/g''(x) = L? -
I like his videos even before they start.
-
How do we decide if we do the limit as it approaches 0 or as it approaches infinity?
-
I like your voice, and thank you so much!
-
thanks a lot again !!!!!!
-
thanks alot!!!!
-
Many thanks!
-
Its because the denominator is being subtracted by a positive number. And the numerator is infinite beacu x just takes infinite
-
These videos are great. Thanks alot
