x 3. Plot f(x)=sin(x) and g(x)=x-++ 120 on the same graph, over the interval (-2,2] and stepsize of h=0.25 for both. Use a MATLAB function m-file to define g(x), and then use feval to evaluate g(x) for the y-values of the plot(s). Compare the graphs, and find the max error over (-2,2] by: (a) Using the graph (b) Using MATLAB's max function max(abs(f- g)) Provide a copy of your.m files and plots along with the errors above. 4. Use mesh to plot the following surfaces on R = {(x,y) - 45x54,-4 sy s 4). Use a stepsize of h =0.1, and graph them separately. (a) f(x,y)=sin(x) cos(y) (b) g(x,y)=sin(x)cos(x) Remember to use. when multiplying. Explain the difference between the two plots. 5. Graph a curve in R'. One option is to complete the example of a 3D line plot in help plot3 (Slinky) or any 3D line function of your choice. Describe your plot.
