this should be done on Excel using VBA. The picture attached has all the details provided. Please take a screenshot of the codes then attach it here. Thank you!

Write a macro to integrate a series of 10 (xv) data points representing an unknown function yaf(x). Show a button to run your macro Write comments (see below for examples) Assume there are ten x/y pairs in the spreadsheet, starting with the first x value in cell A1, and the first y value in cell B1, and the remaining data points organized vertically downward, with all x-values in column A and y values in column B The x-values are equidistant All x and y values are equal or larger than zero. There are no empty spreadsheet cells or irregular entries (letters and such) among the data set To approximate the integral, calculate and sum the areas of rectangles of area A-yi* deltaX where yi is the right hand boundary of each interval bounded by two x-values (see posted pictures of algorithm). deltaX is the distance between two adjacent x-values Output the value of the integral via a message box after the integration Write a macro to integrate a series of 10 (xv) data points representing an unknown function yaf(x).
