The book begins by applying Lagrange's equations to a number of mechanical nates. These are frequently the plane polar coordinates (r, θ ) whose relation to.

Laplace’s equation in the polar coordinate system in details. Recall that Laplace’s equation in R2 in terms of the usual (i.e., Cartesian) (x,y) coordinate system is: @2u @x2 ¯ @2u @y2 ˘uxx ¯uyy ˘0. (1) The Cartesian coordinates can be represented by the polar coordinates as follows: (x ˘r cosµ; y ˘r sinµ. (2) Statement. The Euler–Lagrange equation is an equation satisfied by a function q of a real argument t, which is a stationary point of the functional. S ( q ) = ∫ a b L ( t , q ( t ) , q ˙ ( t ) ) d t {\displaystyle \displaystyle S ( {\boldsymbol {q}})=\int _ {a}^ {b}L (t, {\boldsymbol {q}} (t), {\dot {\boldsymbol {q}}} (t))\,\mathrm {d} t} where: Laplace’s equation in polar coordinates, cont.

In this case, the Euler-Lagrange equations p˙σ = Fσ say that the conjugate momentum pσ is conserved. Consider, for example, the motion of a particle of mass m near the surface of the earth. As another example of a simple use of the Lagrangian formulationof Newtonian mechanics, we find the equations of motion of a particle in rotating polar coordinates, with a conservative "central" (radial) force acting on it.
