Study Notes
Calculus
Introduction
- Calculus is a branch of mathematics that deals with the study of continuous change.
- It is divided into two main branches: Differential Calculus and Integral Calculus.
Differential Calculus
- Deals with the study of rates of change and slopes of curves.
- Key concepts:
- Limits: the value that a function approaches as the input gets arbitrarily close to a certain point.
- Derivatives: a measure of how a function changes as its input changes.
- Differentiation rules: power rule, product rule, quotient rule, and chain rule.
- Geometric interpretation: the derivative of a function at a point represents the slope of the tangent line to the graph of the function at that point.
Integral Calculus
- Deals with the study of accumulation of quantities.
- Key concepts:
- Definite integrals: the area between a curve and the x-axis over a specific interval.
- Indefinite integrals: the antiderivative of a function, which can be used to find the definite integral.
- Integration rules: substitution method, integration by parts, integration by partial fractions, and integration by trigonometric substitution.
- Applications: area between curves, volume of solids, surface area, and work and energy.
Applications of Calculus
- Physics and Engineering: calculus is used to model the motion of objects, including the acceleration and velocity of particles and the curvature of space-time.
- Economics: calculus is used to model economic systems, including the behavior of markets and the impact of policy changes.
- Computer Science: calculus is used in machine learning, data analysis, and algorithm design.
- Biology: calculus is used to model population growth, disease spread, and chemical reactions.
Important Theorems and Formulas
- Fundamental Theorem of Calculus: relates the derivative of an antiderivative to the definite integral of a function.
- Mean Value Theorem: states that a function must have at least one point where the derivative is equal to the average rate of change over an interval.
- Integration by Parts Formula: ∫udv = uv - ∫vdu.

Differential Calculus
Key Concepts
- Limits: value a function approaches as input gets arbitrarily close to a certain point.
- Derivatives: measure of how a function changes as input changes.
-
Differentiation Rules:
- Power Rule: if f(x) = x^n, then f'(x) = nx^(n-1).
- Product Rule: if f(x) = u(x)v(x), then f'(x) = u'(x)v(x) + u(x)v'(x).
- Quotient Rule: if f(x) = u(x)/v(x), then f'(x) = (u'(x)v(x) - u(x)v'(x)) / v(x)^2.
- Chain Rule: if f(x) = g(h(x)), then f'(x) = g'(h(x)) * h'(x).
- Geometric Interpretation: derivative represents the slope of the tangent line to the graph of the function at a point.
Integral Calculus
Key Concepts
- Definite Integrals: area between a curve and the x-axis over a specific interval.
- Indefinite Integrals: antiderivative of a function, used to find definite integrals.
-
Integration Rules:
- Substitution Method: ∫f(g(x)) * g'(x) dx = ∫f(u) du.
- Integration by Parts: ∫udv = uv - ∫vdu.
- Integration by Partial Fractions: breaks down a rational function into simpler fractions.
- Integration by Trigonometric Substitution: uses trigonometric identities to integrate.
- Applications: area between curves, volume of solids, surface area, and work and energy.
