I need to create a function file that contains the commands to plot ? = sin ? and ? = sin2 ? on the same graph, I need to use the following expression to define the range of x in the function x=0:pi/A:2*pi. I then need to test the function using different values of A. Does this make sense?

Write the code, for e.g.
function y=plot(A)
x=0:pi/A:2*pi;
plot(x, sin(x))
hold on
plot(x, sin(2*x))
hold off
end
Call the function in the command window with an arbitary value of 'A'
plot(100) and plotted graphs will come as output. Try to give large values of A to ensure smooth curvesa and make sure the file is saved as the same name as the function.
