- Fundamental Theorem of Calculus: Links differentiation and integration, stating that integration can be reversed by differentiation.
Fractions
- Definition: A way to represent a part of a whole, expressed as a/b where 'a' is the numerator and 'b' is the denominator.
-
Types:
- Proper fractions: Numerator < Denominator.
- Improper fractions: Numerator ≥ Denominator.
- Mixed numbers: A whole number combined with a proper fraction.
-
Operations:
- Addition/Subtraction: Common denominators needed.
- Multiplication: Multiply numerators and denominators.
- Division: Invert the second fraction and multiply.
Perimeter
- Definition: The total distance around a shape.
-
Formulas:
- Rectangle: P = 2(l + w)
- Square: P = 4s (where s = side length)
- Triangle: P = a + b + c (sum of all sides)
- Circle: P (Circumference) = 2πr (where r = radius)
Area
- Definition: The amount of space inside a shape.
-
Formulas:
- Rectangle: A = l × w
- Square: A = s²
- Triangle: A = (1/2) × base × height
- Circle: A = πr² (where r = radius)
- Units: Typically measured in square units (e.g., cm², m²).
Arithmetic
- Focuses on fundamental operations: addition, subtraction, multiplication, division.
- Key operations are represented by symbols:
