Study Notes
Imaginary and Real Numbers
- Imaginary numbers are square roots of negative numbers with no corresponding points on the number line.
- Real numbers have defined locations on the number line and include all rational and irrational numbers.
Types of Numbers
- Negative numbers are values less than zero; examples include -1 or -5.
- Positive numbers are values greater than zero; examples include 1 or 7.
- Zero is a unique number that is neither positive nor negative.
Rational and Irrational Numbers
- Rational numbers can be expressed as a ratio of two integers; examples include 1/2, 2, or -6/12.
- Irrational numbers cannot be expressed as a ratio of integers but are real; examples include √5 and π.
Radicals and Transcendental Numbers
- Radicals involve square roots, cube roots, etc., of integers; for instance, √5.
- Transcendental numbers cannot be expressed as the root of any integer; π is a primary example.
Integer and Non-Integer Types
- Integers encompass whole numbers and their negatives, such as 2 and -2.
- Nonintegers include fractions or numbers that fall between integers, e.g., 3/4 and -7/10.
Natural and Counting Numbers
- Natural (counting) numbers are the set of positive integers starting from 1.
Number Classification
- Digits range from 0 to 9, forming the basis of numerals.
- Even numbers are integers divisible by 2, such as 2 and -4.
- Odd numbers are integers not divisible by 2, such as 3 and -5.
Mathematical Properties
- Axioms are fundamental mathematical properties like closure, commutativity, associativity, identity elements, inverses, and distributivity.
Polynomials
- Polynomials are algebraic expressions formed by the addition, subtraction, or multiplication of variables.
- Types of polynomials based on the number of terms include monomial (1 term), binomial (2 terms), trinomial (3 terms), and polynomial (4 or more terms).
Degree of Polynomial
- The degree of a polynomial indicates the highest number of variables as factors in any term.
- Degrees include: 0 (constant), 1 (linear), 2 (quadratic), 3 (cubic), 4 (quartic), and 5 (quintic).
Solutions and Properties
- An extraneous solution satisfies a transformed equation but not the original.
- The reflexive property asserts that any number is equal to itself (x = x).
- Symmetry states that if x equals y, then y equals x.
- Transitivity defines equality as if x = y and y = z, then x = z; and for order, if x > y and y > z, then x > z.
- Trichotomy states that for real numbers x and y, one and only one of the conditions holds: x > y, y > x, or x = y.
Theorems and Logical Connectives
- A lemma serves as a minor result aiding in the proof of more complex theorems.
- A theorem is a proven mathematical statement applicable in further calculations.
- The logical connective Or allows for possibilities where an equation is greater than or equal to x or less than or equal to -x.
- The logical connective And constrains an equation to being less than or equal to x or greater than or equal to -x.
