Study Notes
Calculus I - Chapter 1: Functions and Limits
- Functions: Defined as a relationship between input (x) and output (y) values.
- Domain: Set of all possible input values (x).
- Range: Set of all possible output values (y).
- Piecewise Defined Functions: Functions defined by different rules on different parts of their domain.
- Symmetry: Functions can be even (symmetric about the y-axis) or odd (symmetric about the origin).
- Composite Functions: A function within another function.
- Limits of Functions: The value a function approaches as the input approaches a certain value.
- One-Sided Limits: Left-hand limit (approaching from the left) and right-hand limit (approaching from the right).
- Continuity: A function is continuous at a point if the limit at that point equals the function value at that point.
- Discontinuity: A point at which a function is not continuous.
- Limits Involving Infinity: The behavior of a function as the input approaches positive or negative infinity.
- Horizontal Asymptotes: Limits as x approaches infinity.
- Vertical Asymptotes: Limits approaching vertical lines.
- Vertical Line Test: A curve in a plane is a function if no vertical line intersects the curve more than once.
Calculus I - Chapter 1: Limit Laws
- Sum/Difference Law: The limit of a sum/difference of functions is the sum/difference of their limits.
- Constant Multiple Law: The limit of a constant times a function is the constant times the limit of the function.
- Product Law: The limit of a product of functions is the product of their limits.
- Quotient Law: The limit of a quotient of functions is the quotient of their limits, provided the denominator's limit isn't zero.
- Power Law: Limit of a function raised to a power is the limit of the function raised to the power.
- Comparison Theorem: If f(x) ≤ g(x) near a, and the limits exist, then limit of f ≤ limit of g.
- Squeeze Theorem: If f(x) ≤ g(x) ≤ h(x) near a, and limits of f and h equal L, then the limit of g is also L.
Calculus I - Chapter 2: Derivatives
- Tangent Line: Line that touches a curve at a single point, representing instantaneous rate of change.
- Average Rate of Change: Change in output over a given interval.
- Instantaneous Rate of Change: Rate of change at a particular point, given by the derivative.
- Derivatives: The instantaneous rate of change of a function.
- Implicit Differentiation: Finding the derivative of a function where the output variable is not explicitly defined in terms of the input variable.
- Related Rates: Finding how one rate of change affects another.
- Linear Approximations: Using a tangent line to approximate a function near a point.
- Differentials: An independent variable with the derivative used to approximate changes in output for a given change in input.
Calculus I - Chapter 3: Inverse Functions
- Definition of Inverse Function: A function f⁻¹ which reverses the action of another function f so that f(f⁻¹(x)) = x and f⁻¹(f(y)) = y
- Horizontal Line Test: A function has an inverse if no horizontal line intersects its graph more than once.
- Cancellation Equation: f⁻¹(f(x)) = x, f(f⁻¹(x)) = x
- Continuity of Inverse Functions: If a function is continuous on an interval, the inverse function is also continuous over its domain.
Calculus I - Chapter 4: Applications of Differentiation
- Absolute/Local Maximum/Minimum: Highest or lowest values a function attains.
- Critical Numbers: Input values where the derivative is zero or undefined.
- Rolle's Theorem: If f is continuous on [a,b], differentiable on (a,b), and f(a) = f(b), then there is a c in (a,b) such that f'(c) = 0
- Mean Value Theorem: If f is continuous on [a,b] and differentiable on (a,b), then there is a c in (a,b) such that f'(c) = (f(b) - f(a)) / (b-a)
- Increasing/Decreasing Functions: Identifies intervals where a function is increasing or decreasing based on the sign of the derivative.
- **Concave Upward/Downward:**Identifies intervals where a function's graph curves upward or downward base on the sign of the second derivative.
