# Lipschitz Continuous
Lipschitz continuous functions are a special case of
continuous functions. Lipschitz continuity means that a cone
can be created with slope less than some real number
$K$.
Fora a real valued function in one dimension, Lipschitz
continuity is defined as:
$$| f(x_1) - f(x_2)| \leq K|x_1 - x_2|$$
Lipschitz continuity can be expanded to vector fields. From
here, we can say that ODE trajectories do NOT intersect, and
that every trajectory is unique.
