Study Notes
Basic Math Concepts
- Arithmetic involves basic operations: addition, subtraction, multiplication, and division.
- Algebra uses variables to represent unknowns and relationships. Solving equations is central.
- Geometry studies shapes, sizes, and positions of figures.
- Trigonometry relates angles and sides of triangles.
- Calculus deals with rates of change and accumulation, including differential and integral calculus.
Number Systems
- Natural numbers are positive integers (1, 2, 3...).
- Whole numbers include natural numbers and zero (0, 1, 2, 3...).
- Integers include whole numbers and their negatives (-3, -2, -1, 0, 1, 2, 3...).
- Rational numbers are fractions p/q (p and q are integers, q ≠ 0).
- Irrational numbers cannot be expressed as fractions. Examples are π and √2.
- Real numbers include all rational and irrational numbers.
- Imaginary numbers contain the square root of -1 (i).
- Complex numbers are of the form a + bi, where a and b are real numbers and i is the imaginary unit.
Arithmetic Operations
- Addition combines values.
- Subtraction finds the difference between values.
- Multiplication scales a value by a factor.
- Division finds how many times one value fits into another.
- Order of operations (PEMDAS/BODMAS): Parentheses/Brackets, Exponents/Orders, Multiplication and Division (left to right), Addition and Subtraction (left to right).
Algebraic Equations
- Equations use an equal sign (=) to relate known and unknown values. Solving involves finding the variable's value.
- Linear equations have a variable to the power of 1.
- Quadratic equations have a variable to the power of 2.
- Systems of equations involve multiple equations. Solutions are intersection points.
Geometric Shapes
- Basic shapes include squares, rectangles, circles, triangles (equilateral, isosceles, scalene).
- Formulas exist for area and perimeter of various shapes.
- 3D shapes include cubes, spheres, cones, and cylinders, with formulas for volume and surface area.
Trigonometric Functions
- Sine, cosine, and tangent relate angles and sides of right-angled triangles.
- These functions are useful in surveying, navigation, and engineering.
Calculus Fundamentals
- Derivatives measure instantaneous rates of change.
- Integrals calculate accumulated values.
- Limits describe function behavior as a variable approaches a value.
- Derivatives and integrals are connected through the fundamental theorem of calculus.
- Calculus applications include finding maximum/minimum values, calculating areas/volumes, and modeling real-world change.
Sets and Relations
- Sets are collections of objects or numbers.
- Relations describe relationships between set elements. Ordered pairs represent relations.
- Functions are special relations where each input maps to one output.
- Domain is the set of all possible inputs.
- Range is the set of all possible outputs.
Important Mathematical Laws and Theorems
- Distributive law: a(b + c) = ab + ac
- Commutative law: a + b = b + a, a * b = b * a
- Associative law: (a + b) + c = a + (b + c), (a * b) * c = a * (b * c)
- Identity properties: Zero addition, one multiplication.
- Inverse properties: Addition (opposite), multiplication (reciprocal).
- Exponent properties (product, quotient, power rule) are key.
- Geometry theorems include triangle congruence and similarity.
