Example 21. Find the general solution of px  The Method of Lagrange multipliers allows us to find constrained extrema. It's more equations, more variables, but less algebra. Example Maximize the function √ f( x , y ) = xy subject to the constraint g(x, y) = 20x + 10y = 200. Using z and f as generalized coordinates, find the Lagrangian L. Write down and solve Lagrange's equations and describe the motion. Solution: We are already  Lagrange's equations for a particle constrained to move on a curved surface ( leaving the general case to Problem 7.13). Section 7.5 offers several examples,  on Position.

Brizard Department of Chemistry and Physics Saint Michael’s College, Colchester, VT 05439 July 7, 2007 Lagrange Interpolation Formula With Example | The construction presented in this section is called Lagrange interpolation | he special basis functions that satisfy this equation are called orthogonal polynomials The Lagrange equation can be modified for use with a very distant object in the following way. In Figure 3.12b, let A represent a very distant object and A′ its image.

Equations (4.7) are called the Lagrange equations of motion, and the quantity. L xi , qxi ,t. (. ) is the Lagrangian. For example, if we apply Lagrange's equation to 

the equations of motion become: mR2θ¨= −mgRsinθ +mR2 sinθcosθφ˙2 d dt mR2 sin2 θφ˙ = 0 If φ˙ = 0 then the first of these looks like the equation of motion for a simple pendulum: θ¨ = −(g/R)sinθ and the quantity in the parenthesis in the second equation is a constant of the motion, a conserved quantity, After combining equations (12) and (13) and algebra: (Ic + mL2 cos 2 ξ)ξ¨ − mL2 ξ˙2 sin ξ cos ξ + mg L cos ξ = 0 4 4 2 Thus, we have derived the same equations of motion. Some comparisons are given in the Table 1.
