Description

In 1915, Emmy Noether discovered a fundamental relationship between symmetries and conservations in physics. Whenever a system is invariant under changes in a particular variable, there is a corresponding conservation of another associated variable.

Particularly notable are the symmetries in:

• Time (conservation of energy),
• Translation (conservation of momentum), and
• Rotation (conservation of angular momentum).

Description

En el espacio de fase la oscilación se puede representar por una elipse

\\n \\nque en forma matemática se escribe como\\n\\n

$\displaystyle\frac{x^2}{a^2}+\displaystyle\frac{y^2}{b^2}=1$

\\n\\nde semiejes a y b se puede representar mediante un parámetro u que va de 0 a 2\pi mediante dos funciones trigonométricas\\n\\n

$x=a\cos u$
