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, and a vector y which is either sin(x), cos(x), tan(x) or cot(x), depending on user specification. then plot with a title that says, e. g. “sin(x) from [0, n]” where the value of n is actually in the title.
