- Standard Deviation: σ = √[Σ(x - μ)^2 / N]
- Probability Density Function (PDF): f(x) = dF(x) / dx
5. **Trigonometry:**
- Sine, Cosine, and Tangent:
- sin(θ) = opposite / hypotenuse
- cos(θ) = adjacent / hypotenuse
- tan(θ) = opposite / adjacent
6. **Probability:**
- Probability of an Event: P(E) = (number of favorable outcomes) / (total number of outcomes)
- Conditional Probability: P(A|B) = P(A ∩ B) / P(B)
- Bayes' Theorem: P(A|B) = [P(B|A) × P(A)] / P(B)
7. **Number Theory:**
- Prime Numbers: Numbers greater than 1 that have no divisors other than 1 and themselves.
- Greatest Common Divisor (GCD): The largest number that divides two or more numbers without leaving a remainder.
- Least Common Multiple (LCM): The smallest multiple that is evenly divisible by two or more numbers.
8. **Linear Algebra:**
- Matrix Multiplication: When multiplying two matrices, the product of an m × n matrix and an n × p matrix results in an m × p matrix.
- Determinant of a Matrix: The determinant is a scalar value that can be computed for a square matrix and is used in various matrix operations.
9. **Differential Equations:**
- First-Order Differential Equation: An equation involving a derivative of an unknown function, such as dy/dx = f(x).
- Second-Order Differential Equation: An equation involving the second derivative of an unknown function, such as d²y/dx² = f(x).
10. **Geometry (3D):**
- Volume of a Cylinder: V = πr²h, where r is the radius of the base and h is the height.
- Volume of a Sphere: V = (4/3)πr³, where r is the radius.
- Surface Area of a Cone: A = πr² + πrl, where r is the radius of the base, l is the slant height.
11. **Calculus (Advanced):**
- Taylor Series Expansion: A representation of a function as an infinite sum of terms involving its derivatives.
- Limits and Continuity: Concepts crucial for understanding the behavior of functions as they approach certain values.
12. **Statistics (Advanced):**
- Confidence Intervals: A range of values within which a population parameter is likely to fall, based on a sample from that population.
- Hypothesis Testing: A statistical method to determine if a hypothesis about a population parameter is supported by sample data.
These formulas cover a wide spectrum of mathematical topics, from advanced calculus and linear algebra to number theory and statistics.
