calcule the first 2 interations of x and y considering the equations: x^2+y^2=4 and y =e^x-2 in matlab

In order to calculate the first 2 iterations of x and y, we can use a numerical method such as Newton's method or the fixed-point iteration method. Let's use the fixed-point iteration method.

First, we need to rearrange the equations so that we have expressions of x and y in terms of themselves:

1. x = sqrt(4 - y^2)
2. y = exp(x) - 2

Now, we can use these expressions to perform the iterations. In Matlab, we can write a script to do this as follows:

main.m
% Initialize the initial guesses for x and y
x0 = 0;
y0 = 0;

% Perform the first iteration
x1 = sqrt(4 - y0^2);
y1 = exp(x0) - 2;

% Perform the second iteration
x2 = sqrt(4 - y1^2);
y2 = exp(x1) - 2;

% Display the results
disp(['x1 = ', num2str(x1)]);
disp(['y1 = ', num2str(y1)]);
disp(['x2 = ', num2str(x2)]);
disp(['y2 = ', num2str(y2)]);

This script will display the values of x and y for the first two iterations. You can modify the initial guesses (x0 and y0) as needed.

Note that the fixed-point iteration method may not always converge to a solution, depending on the chosen initial guesses and the behavior of the equations.
