How do I solve the following difference differential equation . The variable nis the number of iterations to be done. The Fourier law of one-dimensional heat conduction equation in fractal media is investigated in this paper. The Picard’s iterative method gives a sequence of approximations Y1(x), Y2(x), ….., Yk(x) to the solution of differential equations such that the n th approximation is obtained from one or more previous approximations. If is a continuous function that satisfies the Lipschitz condition (1) in a surrounding of , then the differential equation (2) (3) has a unique solution in the interval , where , min denotes the minimum, , and sup denotes the supremum. PICARD ITERATION DAVID SEAL The diﬀerential equation we’re interested in studying is (1) y′ = f(t,y), y(t0) = y0. Picard iterates for the initial value problem y' = f(x,y),y(a) = b are obtained with a task template. This requires multiple iterations over a function being substituted in a to be integrated polynomial. x i+1 = g(x i), i = 0, 1, 2, . Calculate an Iteration. An Ordinary differential equation is an equation relating y, x, first-order derivative of y. In general, you can skip parentheses, but be very careful: e^3x is `e^3x`, and e^(3x) is `e^(3x)`.
