Soil erosion is a widespread problem in rural and urban Queensland. If we want to save our soils, we need to understand the different types of erosion that can occur. Queenslandâs high intensity summer rainfalls represent a significant risk of erosion by water.
Lagrangian function. Lagrangian function, also called Lagrangian, quantity that characterizes the state of a physical system. In mechanics, the Lagrangian function is just the kinetic energy (energy of motion) minus the potential energy (energy of position).
Lagrange Multipliers. The method of Lagrange multipliers is a method for finding extrema of a function of several variables restricted to a given subset. Let us begin with an example.n this section we apply the method of Lagrange multipliers instead. The key to understanding this technique is the following figure, which plots the constraint function and the level curves of f(x,y).
