Study Notes
Overview of Calculus I (MATH 150/151)
- Course focuses on fundamental concepts of calculus, including functions, differentiation, and applications.
- Offers comprehensive coverage of essential mathematical models and theories.
Functions and Models
- Functions relate each element of a domain to a unique element of a codomain.
- Four representations of functions:
- Verbally (e.g., descriptions)
- Algebraically (e.g., formulas)
- Numerically (e.g., tables or sets of ordered pairs)
- Visually (e.g., graphs)
Basic Sets of Numbers
- Natural Numbers: N = {1, 2, 3, ...}
- Integers: Z = {..., -2, -1, 0, 1, 2, ...}
- Rational Numbers: Q = {a/b: a, b ∈ Z, b ≠0}
- Real Numbers: Includes all rational numbers and irrational numbers that fill gaps within the number line.
Defining Functions
- Example: For a function f such that f(x) = x², identify input-values and compute output values.
- Domain represents possible input values; the codomain represents allowable output values.
- Range is the actual output values corresponding to the domain.
Mathematical Models
- Linear Functions: Defined by slope and y-intercept. Can deduce the equation from these parameters.
- Power Functions: Functions of the form f(x) = x^a, where a is a real number.
- Polynomials: Functions expressed as f(x) = a_n * x^n + ... + a_1 * x + a_0, with integer n and coefficients a_i being real numbers.
Graphing Functions
- Vertical line test determines whether a graph represents a function; if any vertical line intersects at most once, it is a function.
- Common function shapes include linear, parabolic, and piecewise functions.
Transformation of Functions
- Transformations of graphs include:
- Shifting vertically (up/down)
- Shifting horizontally (right/left)
- Reflecting across axes
- Example transformations:
- y = f(x) + c shifts upward by c.
- y = f(x) - c shifts downward by c.
Differentiation and Applications
- Concepts of limits and derivatives underpin calculus.
- Derivatives measure rates of change and are essential for understanding curve behavior.
- Applications include optimization problems, curve sketching, and understanding motion.
Exam Preparation
- Practice exercises covering all the course material are necessary.
- Review notes and key concepts regularly.
- Prepare sample problems and check against solutions for mastery.
Appendix and Additional Resources
- Solutions to exercises provided to enhance understanding.
- Bibliography includes articles, books, and web resources for further reading and study.
