Math

Math can be written directly in MDX. Use it near the prose and executable cells that depend on the notation so readers do not have to jump between pages.

Inline Math

Inline math uses single dollar signs. In the logistic map, the state is $x_n \in [0, 1]$ and the parameter is $r \in [0, 4]$.

Subscripts and superscripts also work together: $x_n + x^2$.

Block Math

Block math uses double dollar signs:

$$x_{n+1} = r x_n (1 - x_n)$$ $$x_n + x^2$$

Matrix

$$A = \begin{bmatrix} 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{bmatrix}$$

Aligned Equations

$$\begin{aligned} f(x) &= x^2 + 2x + 1 \\ &= (x + 1)^2 \end{aligned}$$

With a Code Cell

Use an executable cell when readers should verify or vary a formula.

Cell inputs

x

y = x**2 + 2*x + 1
print(f"f({x}) = {y}")

Run the cell to show its output.
