Write a script that will prompt the user for a character. It will create an x-vector that has 50 numbers, equally spaced between -2π and 2π, and then a y-vector which is cos(x)

Write a script that will prompt the user for a character. It will create an x-vector that has 50 numbers, equally spaced between -2π and 2π, and then a y-vector which is cos(x). If the user entered the character ‘r’, it will plot these vectors with red *s – otherwise, for any other character it will plot the points with green +s.
