How to Write LaTeX Math
Basic Formulas
In LaTeX, use \frac{a}{b} for fractions, x^{2} for exponents, x_{i} for subscripts, and \sqrt{x} for square roots. Wrap arguments in braces {}.
| Description | LaTeX Code | Result |
|---|---|---|
| Fraction | \frac{a}{b} | |
| Exponent | x^{2} | |
| Subscript | x_{i} | |
| Square root | \sqrt{x} | |
| Bar (mean) | \bar{x} | |
| Hat (estimate) | \hat{x} |
Calculus
Use \frac{dy}{dx} for derivatives, \frac{\partial f}{\partial x} for partial derivatives, \int_{a}^{b} for integrals, and \lim_{x \to 0} for limits.
| Description | LaTeX Code | Result |
|---|---|---|
| Derivative | \frac{dy}{dx} | |
| Partial derivative | \frac{\partial f}{\partial x} | |
| Definite integral | \int_{a}^{b} f(x) dx | |
| Limit | \lim_{x \to 0} | |
| Summation | \sum_{i=1}^{n} | |
| Product | \prod_{i=1}^{n} |
Linear Algebra
Use \vec{a} for vectors, \begin{pmatrix} ... \end{pmatrix} for matrices. Also supports A^{T} for transpose, A^{-1} for inverse, and \vec{a} \cdot \vec{b} for dot product.
| Description | LaTeX Code | Result |
|---|---|---|
| Vector (arrow) | \vec{a} | |
| Vector (bold) | \boldsymbol{a} | |
| Dot product | \vec{a} \cdot \vec{b} | |
| Norm | \|\vec{a}\| | |
| Parenthesized matrix | \begin{pmatrix} a & b \\ c & d \end{pmatrix} | |
| Bracketed matrix | \begin{bmatrix} a & b \\ c & d \end{bmatrix} | |
| Inverse matrix | A^{-1} | |
| Transpose matrix | A^{T} |
Common Greek Letters
Greek letters commonly used in math and physics can be typed with commands like \alpha and \theta. For uppercase, capitalize the first letter: \Sigma.
| Description | LaTeX Code | Result |
|---|---|---|
| Alpha | \alpha | |
| Beta | \beta | |
| Gamma | \gamma,\ \Gamma | |
| Delta (change) | \delta,\ \Delta | |
| Epsilon | \epsilon,\ \varepsilon | |
| Eta (learning rate) | \eta | |
| Theta | \theta,\ \Theta | |
| Lambda | \lambda,\ \Lambda | |
| Mu (mean) | \mu | |
| Pi | \pi,\ \Pi | |
| Rho (density / correlation) | \rho | |
| Sigma (std. dev. / summation) | \sigma,\ \Sigma | |
| Phi | \phi,\ \Phi | |
| Omega | \omega,\ \Omega |
