Min and Max

This program uses a series of FOR loops and the nSolve() function to determine the max and min points of a given function over a given interval. It works for several more complex equations that solve() and zeros() can’t solve. maxmin(expression, iterations, maximum value, minimum value). Returns answers in the form of a matrix, with the max and min x values in the left column and corresponding y values for the original expression in the right column.
