how do I solve the lim, as x---> infinity, of cos x?

Answer 1

limit doesn't exist

Answer 2

the limit is the derivative of cos(x). Which is -sin(x) when x is infinity then it is -sin(infinity). There is no answer here though, because a limit is when it is approaching a value. The graph of cosx ocsillates between 1 and -1 so it never approaches one specific value. Hope that helps.

Answer 3

limit of cos x does not exist because
cos x alternates between -1 and 1 (y value)

Answer 4

if u look at the graph u see that it oscilates between 1 and -1, so the lim does not exist.
