Anyone know limits...?

Question

If you are trying to find the limit as x approaches five and you get the fraction to be 0 over 0, the limit doesn't exists, right?

Answer 1

MAY OR MAY NOT EXIST DEPENDING ON THE KIND OF FUNCTION IT IS.........
but generally it does exist

Answer 2

There is a theorem that when you have a expression in fraction form, and the limit is indeterminate, a valid limit may sometimes be found by differentiating the numerator and denominator separately, and forming a new fraction with the differentials. If this new expression has a limit, this is also the limit of the original function.

The example that comes to mind is:

lim(sin x / x)|x-->0 is indeterminate.
lim(cos x / 1)|x-->0 = 1.
therefore lim(sin x) = 1
This agrees with the intuitive answer arrived at if you graph the expression.

Answer 3

it is not necessarily right in all cases.... there techniques that can be applied when you get a limit of 0/0... the Le Hospital's rule can be used... but since you did not put the whole equation, i cannot give you a concrete answer...

Answer 4

Sometimes the limit does exist.

Answer 5

it depends on the equation. Limits usually refers to parabolic curves where the chart goes infinitely. if you get the equation 0/0, then the limit is undefined, not dne

Answer 6

when i drink there is a limit its about 2/3 of a 5th

Answer 7

uhhhuhhhhh 1

Answer 8

yes

Answer 9

what is the exact equation? it is true in some cases.

Answer 10

Right!!!!
