Study Notes
Limits and Continuity
- Limits describe the behavior of a function as its input approaches a particular value.
- A limit exists if the function approaches the same value from both sides as the input approaches a certain value.
- Limits are crucial for defining continuity and calculating derivatives.
- Formal definitions of limits exist, involving epsilon-delta proofs.
- Applications of limits include finding asymptotes and instantaneous rates of change.
Derivatives
- Derivatives represent the instantaneous rate of change of a function.
- They are calculated using limit definitions or differentiation rules.
- Some basic differentiation rules include the power rule, sum/difference rule, constant multiple rule, product rule, quotient rule, and chain rule.
- Derivatives help to find maximum and minimum values, sketch graphs, and solve optimization problems.
- Applications of derivatives include velocity, acceleration, marginal cost, and marginal revenue.
Differentiation Rules
- Power Rule: The derivative of xn is nxn-1.
- Sum/Difference Rule: The derivative of (f(x) ± g(x)) is f'(x) ± g'(x).
- Constant Multiple Rule: The derivative of kf(x) is kf'(x).
- Product Rule: The derivative of (f(x)*g(x)) is f'(x)g(x) + f(x)g'(x).
- Quotient Rule: The derivative of (f(x)/g(x)) is (g(x)f'(x) - f(x)g'(x))/(g(x))2.
- Chain Rule: The derivative of (f(g(x))) is f'(g(x))*g'(x).
Integrals
- Integrals are used to find the area under a curve.
- There are two main types:
- Definite integrals: Calculate the area between a curve and the x-axis over a specific interval.
- Indefinite integrals: Find the general antiderivative of a function.
Integration Techniques
- Basic integration rules: Similar to differentiation rules, but reversed.
- Substitution: Using a substitution to simplify an integral.
- Integration by parts: Using the product rule in reverse to solve integrals.
- Trigonometric substitutions: Dealing with integrals involving trigonometric functions.
- Partial fraction decomposition: Breaking down complex rational functions into simpler components.
Applications of Integrals
- Calculating areas and volumes.
- Finding displacement and velocity.
- Solving optimization problems (maximum profit).
- Calculating work.
- Probability and statistics.
Implicit Differentiation
- Differentiating implicitly helps find the derivative of a relation or equation that isn't a function.
- This method is important for relations that aren't expressible in the form y = f(x).
Related Rates
- Related rates problems involve finding the rate of change of one quantity in terms of the rate of change of another related quantity.
- These problems often involve implicit differentiation.
Sequences and Series
- Sequences: Ordered lists of numbers.
- Series: Sums of sequences.
- Types of sequences/series: Arithmetic, geometric, etc.
- Convergence of series: Determining if a series approaches a finite value or diverges.
Applications of Calculus
- Physics: Finding velocity, acceleration, and position.
- Engineering: Optimizing design, calculating work, and modelling systems.
- Economics: Calculating marginal costs and maximizing profits.
- Computer graphics: Generating smooth curves and surfaces.
Additional Concepts
- L'Hôpital's Rule: Used to evaluate limits that involve indeterminate forms (e.g., 0/0, ∞/∞).
- Mean Value Theorem: Guarantees the existence of a point where the instantaneous rate of change equals the average rate of change.
- Fundamental Theorem of Calculus: Establishes the relationship between differentiation and integration.
- Applications of the Fundamental Theorem of Calculus: Finding areas under curves.
