Problem 1. Write a script that will prompt the user for a positive number n and a trigonometric function name, such as sin, cos, tan or cot. Create a vector x of 1000 linearly equally spaced points between 0 and n. Then, by using a function eval, create a vector y which is either sin(r), cos(r), tan(x) or cot(x), depending on user specification. Then plot (x.y) with a title that says: "sin(x) from [0, n]", where the value of n is actually in the title
