Final answer:
To find the stationary functions for the given functionals, we need to use the Euler-Lagrange equation. In part (a), we solve the Euler-Lagrange equation for the functional J[y] = ∫[x₁]^[x₂] (x(y')² - y(x)y'(x) + y(x)) dx. In part (b), we also consider boundary conditions.
Step-by-step explanation:
To find the stationary functions for the given functionals, we need to use the Euler-Lagrange equation. In part (a), we need to solve the Euler-Lagrange equation for the functional J[y] = ∫[x₁]^[x₂] (x(y')² - y(x)y'(x) + y(x)) dx. This will give us the stationary function. In part (b), besides solving the Euler-Lagrange equation, we also have boundary conditions to consider. You mentioned that you tried to find C1 and C2, but it seems that you made a mistake.
