Also, note that the first equation really is three equations as we saw in the previous examples. Let’s see an example of this kind of optimization problem. This function is called the "Lagrangian", and the new variable is referred to as a "Lagrange multiplier". Step 2: Set the gradient of equal to the zero vector.

Such a partial differential equation is known as Lagrange equation. For Example xyp + yzq = zx is a Lagrange equation. Equations (4.7) are called the Lagrange equations of motion, and the quantity L(x i,x i,t) is the Lagrangian.

The chief advantage of the Lagrange equations is that their number is equal to the number of degrees of freedom of the system and is independent of the number of points and bodies in the system.
