delta

delta minuscolo $$$\delta$$$ genera $$\delta$$
delta maiuscolo $$$\Delta$$$ genera $$\Delta$$

derivate

per le derivate si possono usare diverse rappresentazioni:

  • $$$\nabla $$$ genera $$\nabla$$
  • $$$ \partial x$$$ genera $$\partial x$$
  • $$$dx$$$ genera $$dx$$
  • $$$ x' x"$$$ genera $$x' x"$$
  • $$$ \dot x \ddot x$$$ genera $$\dot x \ddot x$$

divisione

$$$x \div y$$$ genera $$x \div y$$

doppia linea verticale (norma)

  • Sintassi: \left\|...\right\|

Exp.: $$$\left\|af\right\| = \left|a\right|\left\|f\right\|$$$ genera $$\left\|af\right\| = \left|a\right|\left\|f\right\|$$
