Final answer:
The Lorenz system is a set of three differential equations used to study convection in the atmosphere. It is used in chaos theory to study the behavior of nonlinear dynamical systems.
Step-by-step explanation:
The Lorenz system is a set of three differential equations used to study convection in the atmosphere. The equations are given as follows:
x = -σx + σy
y = rx -y-x
z = xy-bz
where σ, r, and b are parameters that determine the behavior of the system. The Lorenz system is used in chaos theory to study the behavior of nonlinear dynamical systems.
