Q&A

How do you find the limit of a function?

To find the limit of a function, you analyze its behavior as it approaches a particular value or infinity. This can be done by direct substitution, factoring, or using special limit rules.

What are asymptotes?

Asymptotes are lines that a curve approaches but never intersects. They can be vertical, horizontal, or oblique, and provide information about the behavior of the function as x approaches infinity or negative infinity.

What is the squeeze theorem?

The squeeze theorem states that if two functions, lower and upper bounds, both approach the same limit as x approaches a particular value, then the function being squeezed between them also approaches that limit.

How do you find horizontal asymptotes?

To find horizontal asymptotes, evaluate the behavior of the function as x approaches infinity or negative infinity. Depending on the degree of the polynomial, the limit will approach a constant or infinity.

How do trigonometric functions affect limits?

Trigonometric functions such as sine and cosine have specific oscillation and amplitude patterns that impact the behavior of limits. Understanding these patterns is crucial in evaluating complex limits involving trigonometric functions.
