Study Notes
Introduction to Calculus
- Calculus is a branch of mathematics that studies change.
- It has two main branches: differential and integral calculus.
- Differential calculus examines rates of change, like the slopes of curves.
- Integral calculus finds areas and volumes.
- These branches work together.
Differential Calculus
-
Derivatives: A derivative shows the instantaneous rate of change of a function at a point.
- Geometrically, it's the slope of the tangent line at that point.
- Mathematically, it's the limit of the difference quotient as the change in x approaches zero.
-
Rules for finding derivatives:
- Power rule: d(xn)/dx = nxn-1
- Sum/difference rule: d(f(x) ± g(x))/dx = d(f(x))/dx ± d(g(x))/dx
- Product rule: d(f(x)g(x))/dx = f'(x)g(x) + f(x)g'(x)
- Quotient rule: d(f(x)/g(x))/dx = [g'(x)f(x) - f'(x)g(x)] / [g(x)]2
- Chain rule: d(f(g(x)))/dx = f'(g(x))g'(x)
-
Applications of derivatives:
- Finding maximum and minimum values of functions (optimization problems).
- Calculating velocity and acceleration of objects.
- Curve sketching (understanding critical points, concavity, and points of inflection).
Integral Calculus
- Integrals: An integral represents the area under a curve.
-
Indefinite integrals: An indefinite integral gives a family of functions whose derivative is the original function. It includes an arbitrary constant.
- Notation: ∫f(x)dx
-
Definite integrals: A definite integral finds the area under a curve between specific limits.
- Notation: ∫ab f(x)dx
-
Fundamental theorem of calculus: Links differentiation and integration.
- Part 1: The derivative of the integral of a function is the function itself.
- Part 2: The definite integral can be found by evaluating the antiderivative at the upper and lower limits and subtracting.
-
Techniques of integration:
- Substitution (u-substitution)
- Integration by parts
- Partial fraction decomposition
- Trigonometric integrals
Applications of Calculus
- Physics: Calculating velocity, acceleration, work, fluid pressure, and moments of inertia.
- Engineering: Bridge and building design, circuit analysis, fluid dynamics, and optimal design.
- Economics: Optimal production levels, marginal cost, and profit maximization.
- Computer Science: Image processing and machine learning optimization.
- Biology: Population growth, drug concentration, and disease spread modeling.
- Statistics: Finding areas under curves in probability distributions and calculating various areas/volumes.
Concepts in Calculus
- Limits: Describes the behavior of a function as its input approaches a value.
- Continuity: A function is continuous if the limit equals the function's value at a point.
- Continuity and differentiability: Differentiable functions are always continuous, but not all continuous functions are differentiable.
Common Errors and Misconceptions in Calculus
- Mistaking limits with infinite limits.
- Errors in applying derivative or integration rules.
- Forgetting the constant of integration in indefinite integrals.
- Calculating limits incorrectly or overlooking them.
- Choosing the wrong calculus concept.
Further Study

- Advanced integration techniques
- Differential equations
- Multivariable calculus
