Create these vectors in MATLAB using both colon(:) and linspace

command:

a. X = [2,4,6,8, , 100];

b. Y = [1, 0.75, 0.5, 0.25, 0, -0.25, 1]

2. Plot cos(5X) and cos(X) in the same figure using hold on command

in MATLAB. The X value can be taken from problem 1. The x- axis

should have a label as time and y-axis should have a label as

amplitude. Put a legend also as function1 and function2
