Question

find limit f(x) = root of x - x / root of x + x when x is heading towards 0

Answer 1

Sorry for deleting my post. I thought conjugates would work, but I was again mistaken lol. Yeah, go ahead and appy L'Hopital's Rule as I said.

Answer 2

Hehe n.p What is the l'hopital's rule i don't know it can you solve it :/

Answer 3

L'Hopital's Rule only applies to limits that are in indefinite forms, like 0/0, inf/inf, 0^0

Answer 4

\[\lim_{x \rightarrow b} \frac{ g(x) }{ h(x) } = \lim_{x \rightarrow b} \frac{ g'(x) }{ h'(x)}\]

Answer 5

It's not the proper way to write it ^^ but it helps.
g(x) and h(x) are in the parent function f(x)

Answer 6

Write the derivative of the numerator, and find the derivative of the denominator. It should work out nicely now.

Answer 7

Oh i got it thanks
