i can do it without using l'hospitals rule but i have to
@satellite73 @surjithayer @jim_thompson5910
so take the derivative of numerator and denominator...
i did and i got \[1/(x/\sqrt(x^2+1))\]
\[\large \lim_{x \to \infty} {x \over \sqrt{x^2+1}}\]
but after you differentiate both dont you have to keep doing it continually because it never stops being an indeterminate?
right ... \[\large = \lim_{x \to \infty} { \sqrt{x^2+1}\over x}\] ... looks like you're right
why use l'hopital? just asking
the answer is 1 right?
sure
eyeball this one
thats what we are learning right now in class. i know its 1 because i can solve it without l'hopitals
well that is a fine how do you do if you use l'hopital the first thing you get is \[\frac{\sqrt{x^2+1}}{x}\] right ?
never mind i read the directions wrong. we're supposed to solve it without l'hopitals and solve a different way. sorry for the trouble
which tells you one thing, if the limit exists and is say \(L\) then \(L=\frac{1}{L}\)
