First, the metric for the plane in polar coordinates is ds2 = dr2 + r2d˚2 (22) Then the distance along a curve between Aand Bis given by S= Z B A ds= Z B These equations are called Lagrange's Equations. If a potential energy exists so that Q_k is derivable from it, we can introduce the Lagrangian Function, L. Where we have used the fact that the derivative of the potential function with respect to the coordinates is the force, and the fact that T depends on both the coordinates and their velocities, while V only depends on the coordinates. The Lagrangian formulation, in contrast to Newtonian one, is independent of the coordinates in use. The Euler--Lagrange equation was first discovered in the middle of 1750s by Leonhard Euler (1707--1783) from Berlin and the young Italian mathematician from Turin Giuseppe Lodovico Lagrangia (1736--1813) while they worked together on the Hamilton's equations are often a useful alternative to Lagrange's equations, which take the form of second-order differential equations. Consider a one-dimensional harmonic oscillator. The kinetic and potential energies of the system are written and , where is the displacement, the mass, and .

Note that they apply to any set of generalized coordinates For domains whose boundary comprises part of a circle, it is convenient to transform to polar coordinates.

My doubt is, Is it legal to write the position vector in any vector basis say polar basis but having components which are functions of $x$, $y$ and then use the Lagrange equation? $$\vec r = f(x,y) \hat e_r + g(x,y) \hat e_\theta$$

Using the Euler–Lagrange equations, this can be shown in polar coordinates as follows. In the absence of a potential, the Lagrangian is simply equal to the kinetic energy L = 1 2 m v 2 = 1 2 m ( x ˙ 2 + y ˙ 2 ) {\displaystyle L={\frac {1}{2}}mv^{2}={\frac {1}{2}}m\left({\dot {x}}^{2}+{\dot {y}}^{2}\right)}
