Study Notes
Branches of Mathematics
- Arithmetic deals with basic operations like addition, subtraction, multiplication, and division.
- Algebra uses variables to represent unknown quantities and solve equations.
- Geometry studies shapes, sizes, and positions of figures in space.
- Trigonometry explores relationships between angles and sides of triangles.
- Calculus involves concepts like limits, derivatives, and integrals, used in analyzing change and accumulation.
- Statistics deals with collecting, organizing, analyzing, and interpreting data.
- Probability studies the likelihood of events occurring.
Fundamental Concepts
- Sets are collections of objects.
- Functions relate input values to output values.
- Variables are symbols representing unknown quantities.
- Equations express equality between two expressions.
- Inequalities show that one expression is greater than, less than, or equal to another.
- Sequences are ordered lists of numbers.
- Series involve the sum of a sequence of numbers.
Number Systems
- Natural numbers (1, 2, 3, ...) are used for counting.
- Whole numbers include all natural numbers and zero.
- Integers include positive and negative whole numbers and zero.
- Rational numbers can be expressed as fractions.
- Irrational numbers cannot be expressed as fractions, like π (pi) and √2.
- Real numbers encompass all rational and irrational numbers.
- Complex numbers include real and imaginary numbers.
Operations
- Addition combines quantities.
- Subtraction finds the difference between quantities.
- Multiplication scales a quantity.
- Division distributes a quantity.
- Exponents indicate repeated multiplication.
- Roots relate to repeated division or multiplication.
- Order of Operations (PEMDAS/BODMAS): Parentheses/Brackets, Exponents/Orders, Multiplication/Division (from left to right), Addition/Subtraction (from left to right).
Properties of Numbers
- Commutative property: order doesn't matter for addition and multiplication.
- Associative property: grouping doesn't matter for addition and multiplication.
- Distributive property: multiplication distributes over addition.
- Identity property: adding zero or multiplying by one doesn't change a number.
- Inverse property: opposite operations cancel each other out.
Geometry Principles
- Shapes have different properties like area, perimeter, and volume.
- Euclidean geometry deals with flat surfaces.
- Non-Euclidean geometry deals with curved surfaces.
- Congruent figures have identical shapes and sizes.
- Similar figures have the same shape but different sizes.
- Theorems are statements that can be proven.
- Postulates are statements that are accepted as true without proof.
Mathematical Problem Solving
- Define the problem.
- Gather relevant information.
- Formulate a strategy.
- Solve the problem.
- Check the answer.
Applications of Mathematics
- Physics uses mathematics to model physical phenomena.
- Engineering uses mathematics to design and build structures.
- Computer science uses mathematics for algorithms and data analysis.
- Finance uses mathematics for investment strategies and risk management.
- Biology uses mathematics to model population growth and genetics.
Different Types of Equations
- Linear equations: represent straight lines on a graph.
- Quadratic equations: involve a squared term.
- Polynomial equations: include more complex terms.
- Exponential equations: involve exponents.
- Trigonometric equations: involve trigonometric functions.
- Logarithmic equations: involve logarithms.
Important Mathematical Symbols
- = (equals) symbol denotes equality.
-
(greater than) and < (less than) are used in inequalities.
- ≠ (not equal to) indicates inequality
- ± (plus or minus) signifies multiple possible values.
- √ (square root) extracts the square root of a value.
- π (pi) is the ratio of a circle's circumference to its diameter
- ∑ (sigma) indicates summation.
