HW9 - 2ab

THESE ARE THE NOTES WE ARE ASKED TO USE.

Use the slides in order to de To rive the method behind Multivariable Newton's method (a) Code in MATLAB. Use surf (x,y,Z) to plot the following surface: fi(x, y) - 2 36. x,y - linspace (-10,10,100) and Z is a (100 x 100) matrix of f(x, y) values (b) Code in MATLAB. Make a second plot for fa(x, y)2-3y-16. The intersection of these two surfaces will be a 3-dimensional curve. In how many places does this curve intersect the = 0 plane
