limit of sin x x as x approaches infinity The easiest use of the squeeze theorem for lim x to pm infty frac sin f x x is frac 1 x le frac sin f x x le frac 1 x so the limit is 0
We use the squeeze theorem to evaluate the limit of sinx x as x approaches infinity This is easy as soon as we recall 1 is less than or equal to sin x is less than or equal to Free Limit at Infinity calculator solve limits at infinity step by step

6 Answers Sorted by 44 Assume x neq 0 and divide the given term by x to get the form frac 1 1 frac sin x x This clearly tends to 1 as x rightarrow infty since 1 le sin x le1 Share For specifying a limit argument x and point of approach a type x a For a directional limit use either the or sign or plain English such as left above right or below limit sin x x as x 0 limit 1 1 n n as n infinity lim x h 5 x 5 h as h 0 lim x 2 2x 3 x 2 2x 3 as x 3 lim x x as
As x approaches infinity the y value oscillates between 1 and 1 so this limit does not exist Thus the answer is it DNE does not exist One good rule to have while solving these problems is that generally if there is no x in the denominator at all then the limit does not exist Example lim x oo sinx DNE lim x oo sinx x 0 It is important to note that by saying lim limits x to c f x infty we are implicitly stating that textit the limit of f x as x approaches c does not exist A limit only exists when f x approaches an actual numeric value

Lim x 1 x 0 In other words As x approaches infinity then 1 x approaches 0 When you see limit think approaching It is a mathematical way of saying we are not talking about when x but we know as x gets bigger the answer gets closer and closer to 0 The limit of an oscillating function f x as x approaches positive or negative infinity is undefined In the plot that you just created try replacing sin with various other trigonometric functions such as cos tan sec csc cot or any of the arc functions like arctan to observe whether they oscillate or whether they have a
