Fit this exponential expression to a function and make the least squares approximation. Then solve the ODE below;

dx/dt = [ 2,5 - y(t) - x(t)*14,3 ] * 1,07 ODE equation

For the time interval t [0, 800] ms using the step sizes t = 40 ms and assume that y(0) = 0 for t = 0 s;

Write the MATLAB code that solves the ODE equation with the Euler Method and find the values of x(t) and y(t). Plots of x(t) and y(t) versus time t.
