How do you calculate Lagrange?
The Lagrangian is L = T −V = m ˙y2/2−mgy, so eq. (6.22) gives ¨y = −g, which is simply the F = ma equation (divided through by m), as expected.
The solution is y(t) = −gt2/2+v0t+y0, as we well know.
But the initial conditions tell us that v0 = y0 = 0, so our solution is y(t) = −gt2/2.If we want to minimise f(x) subject to the inequality constraints, we need to write the inequality con- straints in the form g1(x) ≥ b1, ··· , gk(x) ≥ bk, i = 1, k.
The key point is the ≥, different from the ≤ occurring when we want to maximise f.
How do you solve Lagrange multiplier problems?
Problem-Solving Strategy: Steps for Using Lagrange Multipliers
1Determine the objective function f(x,y) and the constraint function g(x,y).2) Set up a system of equations using the following template: ⇀∇f(x0,y0)=λ⇀∇g(x0,y0)g(x0,y0)=0.
3) Solve for x0 and y0.
What is the Lagrange multiplier method?
Lagrange multiplier method is a technique for finding a maximum or minimum of a function F(x,y,z) subject to a constraint (also called side condition) of the form G(x,y,z) = 0.
