A Lagrange equation' is a first-order differential equation that is linear in both the dependent and independent variable, but not in terms of the derivative of the dependent variable. Explicitly, if the independent variable is and the dependent variable is , the Lagrange equation has the form: Normalized for the dependent variable

Lagrange’s Linear Equation . Equations of the form Pp + Qq = R _____ (1), where P, Q and R are functions of x, y, z, are known as Lagrang solve this equation, let us consider the equations u = a and v = b, where a, b are arbitrary constants and u, v are functions of x, y, z. To calculate the Euler Lagrange equation I have the following: $$\frac{d}{dx}(2y^2y')-2y^2\frac{dy}{dx}+2\lambda y=0$$. Is this correct?

### follows: expand the original equation to ﬁrst order α and consider a solution of the form z = 1+ λα and put it into the equation, discard all higher order terms α2, α3 and so on and then determine λ. We now show this does not work, why it does not work and how to proceed in this and similar cases. If we use the expansion 1 (1+α)2
