Discretization basics for range of dx- Effect of dx on error

Objective: To compute the first, second and fourth-order approximations for a given value of x. For this program, you need to do the following.1. For a range of dx, plot the first order, second and fourth-order error.2. Make sure that you plot dx vs error in a way that makes sense.3. Explain the results in the space provided.…

Week 6 - Multivariate Newton Rhapson Solver

Objective:

Objective: To solve a given set of Ordinary Differential equations using the Multi-Variate Newton Raphson Method. Given: The set of ODE's are given below: $\frac{{d y}_{1}}{d t} = - 0.04 \cdot y_{1} + 10^{4} \cdot y 2 \cdot y 3$ $dy_1/dt= - 0.04*y_1+10^4*y2*y3$ $dy_2/dt=0.04*y_1-10^4*y_2*y_3-3*10^7*y_2^2$ $dy_3/dt=3*10^7*y_2^2$ The jacobian should be estimated numerically and not analytically.…
