MATLAB QUESTION
2*x^2 + y^2 = 24
x^2-y^2=12
Use first an initial guess x=3,y=4 and then use a second guess of x=-1,y=2.
What are the solutions of each?
Plot each of the equations
find how many solutions or points of intersection exist.
Should be done on matlab

In MATLAB please
Consider the nonlinear function: y = f(x) = x3 cos x a. Plot y as a function of x as x is varied between -67 and 67. In this plot mark all the locations of x where y = 0. Make sure to get all the roots in this range. You may need to zoom in to some areas of the plot. These locations are some of the roots of the above equation. b. Use the fzero...

1. The function f(z, y) (a-x)2 + b(y-12)2 is called Rosenbrock's banana function. It is often used as a benchmarking test for optimization algorithms becatse it is easy to find the minimum by hand but often very difficult to find numerically. Throughout the problem, we will use the values a = 2 and b 10. You can plot this function using the following code: x3:0.1:3; y = -10:0.2:10; Cx,Ymeshgrid(x,y); Z(2-X).2 10* (Y-X. 2)....
