The Helmholtz equation represents a time-independent form of the wave equation It is written as follows d^2u/dx^2(x) + k^2u(x) = f(x) with k = 10 1. Set h = 0.05 and using a centered apprcramation of the second derivative of u, you can approximate the Helmhdtz equation with the algebraic equation lphaau(x + H) +betau(x) + u(x - h) = f(x) Find the coefficients alpha, beta, and gramma. TASK: Save the coefficient a in the fie A07.dat, the coefficient beta in the file A08.dat, and the coefficient lambda in the file A09.dat
