Study Notes
Rates of Change and Tangent Lines
- A rate of change is a measure of how fast something changes with respect to another variable
- Tangent lines to curves are used to analyze the rate of change at a specific point
Limits of Functions
- The limit of a function is a value that the function approaches as the input gets arbitrarily close to a certain point
- Limit laws are used to evaluate limits by breaking down a function into simpler components
- The precise definition of a limit involves using delta-epsilon notation to define the limit of a function
One-Sided Limits
- One-sided limits are used to evaluate the limit of a function from a specific direction (left or right)
- One-sided limits are used to analyze the behavior of a function at a specific point
Continuity
- A function is continuous at a point if the limit of the function exists at that point
- Continuity is a fundamental property of functions that is used to analyze their behavior
Limits Involving Infinity
- Limits involving infinity are used to analyze the behavior of a function as the input grows without bound
- Asymptotes of graphs are used to visualize the behavior of a function as the input grows without bound
Derivatives
- The derivative of a function at a point is a measure of the rate of change of the function at that point
- The derivative of a function can be used to find the slope of the tangent line to the function at a point
- Differentiation rules are used to find the derivative of a function, such as the power rule, product rule, and quotient rule
Derivative as a Rate of Change
- The derivative of a function can be interpreted as a rate of change, which is used to analyze the behavior of the function
- The derivative of a function is used to find the maximum and minimum values of the function
