# Mathematical Formulas and Expressions
|
|
|
|
This document demonstrates various mathematical notation and formulas that can be rendered using LaTeX syntax in markdown.
|
|
|
|
## Basic Arithmetic
|
|
|
|
### Addition and Summation
|
|
$$\sum_{i=1}^{n} i = \frac{n(n+1)}{2}$$
|
|
|
|
## Algebra
|
|
|
|
### Quadratic Formula
|
|
The solutions to $ax^2 + bx + c = 0$ are:
|
|
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
|
|
|
|
### Binomial Theorem
|
|
$$(x + y)^n = \sum_{k=0}^{n} \binom{n}{k} x^{n-k} y^k$$
|
|
|
|
## Calculus
|
|
|
|
### Derivatives
|
|
The derivative of $f(x) = x^n$ is:
|
|
$$f'(x) = nx^{n-1}$$
|
|
|
|
### Integration
|
|
$$\int_a^b f(x) \, dx = F(b) - F(a)$$
|
|
|
|
### Fundamental Theorem of Calculus
|
|
$$\frac{d}{dx} \int_a^x f(t) \, dt = f(x)$$
|
|
|
|
## Linear Algebra
|
|
|
|
### Matrix Multiplication
|
|
If $A$ is an $m \times n$ matrix and $B$ is an $n \times p$ matrix, then:
|
|
$$C_{ij} = \sum_{k=1}^{n} A_{ik} B_{kj}$$
|
|
|
|
### Eigenvalues and Eigenvectors
|
|
For a square matrix $A$, if $Av = \lambda v$ for some non-zero vector $v$, then:
|
|
- $\lambda$ is an eigenvalue
|
|
- $v$ is an eigenvector
|
|
|
|
## Statistics and Probability
|
|
|
|
### Normal Distribution
|
|
The probability density function is:
|
|
$$f(x) = \frac{1}{\sigma\sqrt{2\pi}} e^{-\frac{1}{2}\left(\frac{x-\mu}{\sigma}\right)^2}$$
|
|
|
|
### Bayes' Theorem
|
|
$$P(A|B) = \frac{P(B|A) \cdot P(A)}{P(B)}$$
|
|
|
|
### Central Limit Theorem
|
|
For large $n$, the sample mean $\bar{X}$ is approximately:
|
|
$$\bar{X} \sim N\left(\mu, \frac{\sigma^2}{n}\right)$$
|
|
|
|
## Trigonometry
|
|
|
|
### Pythagorean Identity
|
|
$$\sin^2\theta + \cos^2\theta = 1$$
|
|
|
|
### Euler's Formula
|
|
$$e^{i\theta} = \cos\theta + i\sin\theta$$
|
|
|
|
### Taylor Series for Sine
|
|
$$\sin x = \sum_{n=0}^{\infty} \frac{(-1)^n}{(2n+1)!} x^{2n+1} = x - \frac{x^3}{3!} + \frac{x^5}{5!} - \frac{x^7}{7!} + \cdots$$
|
|
|
|
## Complex Analysis
|
|
|
|
### Complex Numbers
|
|
A complex number can be written as:
|
|
$$z = a + bi = r e^{i\theta}$$
|
|
|
|
where $r = |z| = \sqrt{a^2 + b^2}$ and $\theta = \arg(z)$
|
|
|
|
### Cauchy-Riemann Equations
|
|
For a function $f(z) = u(x,y) + iv(x,y)$ to be analytic:
|
|
$$\frac{\partial u}{\partial x} = \frac{\partial v}{\partial y}, \quad \frac{\partial u}{\partial y} = -\frac{\partial v}{\partial x}$$
|
|
|
|
## Differential Equations
|
|
|
|
### First-order Linear ODE
|
|
$$\frac{dy}{dx} + P(x)y = Q(x)$$
|
|
|
|
Solution: $y = e^{-\int P(x)dx}\left[\int Q(x)e^{\int P(x)dx}dx + C\right]$
|
|
|
|
### Heat Equation
|
|
$$\frac{\partial u}{\partial t} = \alpha \frac{\partial^2 u}{\partial x^2}$$
|
|
|
|
## Number Theory
|
|
|
|
### Prime Number Theorem
|
|
$$\pi(x) \sim \frac{x}{\ln x}$$
|
|
|
|
where $\pi(x)$ is the number of primes less than or equal to $x$.
|
|
|
|
### Fermat's Last Theorem
|
|
For $n > 2$, there are no positive integers $a$, $b$, and $c$ such that:
|
|
$$a^n + b^n = c^n$$
|
|
|
|

|
|
|
|
### De Morgan's Laws
|
|

|
|
$$\overline{A \cap B} = \overline{A} \cup \overline{B}$$
|
|
|
|
## Advanced Topics
|
|
|
|
### Riemann Zeta Function
|
|
$$\zeta(s) = \sum_{n=1}^{\infty} \frac{1}{n^s} = \prod_{p \text{ prime}} \frac{1}{1-p^{-s}}$$

|
|
|

|
|
$$\nabla \cdot \mathbf{B} = 0$$
|
|
$$\nabla \times \mathbf{E} = -\frac{\partial \mathbf{B}}{\partial t}$$
|
