Simply saying, it's just the SLOPE of ONE POINT of a graph (line or curves or anything). Both sides' limits are 5, so the limit exists, and is 5.If the results are exactly the same, then the limit is the result Otherwise the limit doesn't exist.Replace cos(x) to ☑ in the equation, 3/☑.

Get that right side 3/-1 = -1 and left side 3/1 =1 is not equal.Know that -1 ≦ cos(x) ≦ 1, so we can tweak it to apply the squeeze theorem to get its limit.The KEY point is to apply the Squeeze theorem, and it is a MUST.
