### Limits Involving Exponential and Logarithmic Functions

Limits involving exponential and logarithmic functions can be evaluated using the following rules:

1. If the exponent is a constant, then the limit is the value of the function evaluated at the given point.
2. If the exponent is a variable, then the limit is the value of the function evaluated at the given point, if the exponent is a constant times the limit of the exponent, and the function is continuous at the given point.
3. If the exponent is a logarithm, then the limit is the value of the function evaluated at the given point, if the logarithm is a constant times the limit of the logarithm and the function is continuous at the given point.

### Limits Involving Trigonometric Functions

Limits involving trigonometric functions can be evaluated using the following rules:

1. If the function is a constant times a trigonometric function, then the limit is the value of the trigonometric function evaluated at the given angle, if the constant is the limit of the constant and the function is continuous at the given angle.
2. If the function is a sum or difference of trigonometric functions, then the limit is the sum or difference of the limits of the individual functions.
3. If the function is a product or quotient of trigonometric functions, then the limit is the product or quotient of the limits of the individual functions, if the limits exist.

### Evaluating Limits at Infinity

Limits at infinity can be evaluated by finding the behavior of the function as the variable approaches infinity. This can be done by:

1. Dividing both the numerator and denominator by the highest power of the variable.
2. Factoring out any common factors.
3. Setting the variable equal to infinity and solving for the limit.

### Using Limits to Find Derivatives

Limits can be used to find derivatives by using the definition of the derivative as the limit of the difference quotient. The difference quotient is the slope of the tangent line to the function at a given point. By finding the limit of the difference quotient as the change in x approaches zero, the derivative can be found.

### Finding Limits Algebraically

Limits can be found algebraically by using the following rules:

1. If the limit of a constant times a function is a constant, then the limit is the constant.
2. If the limit of a sum or difference of functions is the sum or difference of the limits of the individual functions, then the limit is the sum or difference.
3. If the limit of a product or quotient of functions is the product or quotient of the limits of the individual functions, then the limit is the product or quotient.

In conclusion, the concept of limits is an important tool in calculus and is used to find derivatives, evaluate functions at points where the function is not defined, and to understand the behavior of functions as the input approaches certain values. Understanding the different types of limits and how to evaluate them is essential for mastering calculus.
