Study Notes
- Calculus is the mathematical study of continuous change, similar to how geometry studies shape and algebra studies generalizations of arithmetic operations.
- It has two major branches: differential calculus and integral calculus.
- Differential calculus deals with instantaneous rates of change and slopes of curves.
- Integral calculus deals with the accumulation of quantities and areas under or between curves.
- These two branches are linked by the fundamental theorem of calculus.
- Calculus is used to find the maximum or minimum value of a function.
Differential Calculus
- Differential calculus studies the definition, properties, and applications of the derivative of a function.
- Finding the derivative is called differentiation.
- Given a function and a point in its domain, the derivative at that point is the slope of the tangent line to the function's graph at that point.
- The derivative helps analyze a function's behavior, including finding its maxima, minima, concavity, and inflection points.
- Derivatives are used in many areas of mathematics, science, and engineering.
- The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point.
Integral Calculus
- Integral calculus studies the definitions, properties, and applications of indefinite and definite integrals.
- Finding the value of an integral is called integration.
- The indefinite integral, or antiderivative, reverses the operation of differentiation.
- F(x) is an indefinite integral of f(x) if f(x) is a derivative of F(x).
- The definite integral takes a function as input and returns a number representing the area between the input's graph and the x-axis.
- Integration is used to find area, volume, center of mass, and probability.
Fundamental Theorem of Calculus
- This theorem connects differentiation and integration.
- Part 1 states that if f is a continuous real-valued function on a closed interval [a, b], then the function F defined for x in [a, b] by F(x) = ∫ₐˣ f(t) dt is continuous on [a, b], differentiable on the open interval (a, b), and F'(x) = f(x) for all x in (a, b).
- Part 2 states that if f is a real-valued function continuous on [a, b] and F is an antiderivative of f on [a, b], then ∫ₐᵇ f(x) dx = F(b) - F(a).
- A consequence is that definite integration can be reversed by differentiation.
- The theorem is applied to solve many differential equations.
Limits and Continuity
- The concept of a limit is fundamental to calculus.
- Differentiation and integration rely on limits to find instantaneous rates of change or to sum infinite infinitesimal quantities.
- A function's limit is the value it approaches as the input approaches some value.
- A function is continuous at a point if the limit of the function as x approaches that point equals the function's value at that point.
- If a function is continuous at all points in its domain, it is said to be continuous.
- Most functions in calculus are continuous at all points in their domain.
Applications of Calculus
- Calculus has wide-ranging applications across various fields.
- In physics, it calculates velocity, acceleration, models gravity, and fluid flow.
- In engineering, it designs structures like bridges and airplanes.
- In economics, it models supply and demand and maximizes profits.
- In statistics, it calculates probabilities and tests hypotheses.
- Calculus finds the area of irregular shapes, the length of curves, and the volume of solids.
- In optimization, calculus helps find the maximum or minimum value of a function, subject to constraints.
