Best ResponseYou've already chosen the best response.0A problem in which the limit does not exist literally does not have any value. Whereas a limit that is infinity does have a value  it's just infinity. For example, \[\lim_{x \rightarrow \infty}x^2\] \lim_{x \rightarrow \infty}cos(x) \] In the first case the limit is \( \infty \) because the function obviously keeps getting larger and larger as you let x go to \( \infty \). In the second case the limit does not exist because as you let x go to \( \infty \) the function does not approach any value (or \( \infty \) ). Remember that in order for a limit to exist the function must be approaching a value as you let x appoach whatever value you are using ( \( \infyt \) ) in this case...

Best ResponseYou've already chosen the best response.0Arg, couldn't type in my math... The second limit should be, \[\lim_{x \rightarrow \infty}cos(x) \]
