hi there,

A limit in trigonometric functions refers to the value that a trigonometric function approaches as its input variable approaches a certain value. It is denoted by the notation lim f(x), where x is the input variable and f(x) is the trigonometric function.
To find the limit of a trigonometric function algebraically, you can use the following techniques: direct substitution, factoring, rationalization, and trigonometric identities. You can also use L'Hopital's rule if the limit involves indeterminate forms such as 0/0 or ∞/∞.
The Squeeze Theorem, also known as the Sandwich Theorem, states that if two functions, g(x) and h(x), are both approaching the same limit L as x approaches a certain value, and f(x) is squeezed between g(x) and h(x), then f(x) also approaches the limit L as x approaches the same value. This theorem is often used to find limits of trigonometric functions by finding two simpler functions that squeeze the trigonometric function between them.
Yes, you can use a graph to estimate the limit of a trigonometric function. By plotting the function and approaching the input value from both sides, you can see if the function is approaching a specific value or if the limit does not exist. However, this method is not always accurate and should be used as a visual aid rather than a definitive answer.
Yes, there are a few special cases when finding limits of trigonometric functions. One case is when the input value is approaching the asymptotes of the function. In this case, the limit does not exist. Another case is when the input value is approaching a value where the function is undefined, such as when the denominator of a fraction is approaching 0. In this case, the limit also does not exist.
