Drag this box down until you reach the other end of your X range, in this case 5. It's hard to describe, look at the third picture. Place your cursor over the bottom-right corner of the cell, there should be a small black square, click it and drag it down, as you drag it, you should see the numbers slowly getting bigger. The dollar signs tell your spreadsheet program to reference A2 regardless of which cell you copy the equation into. Then in the cell below (B2) type in "=B1+$A$2" without the quotation marks, hit enter. Put your initial value at the top of the next column over, the second picture below shows you what this should look like. For my computer, below 1000 cells usually works well. Once your columns are more than a few thousand cells long, it takes forever for your computer to process them all at once. You could also use 0.01 (it would be a bit more accurate) but you generally don't want to go smaller. Also set your step size, I set mine at 0.1. First, you want to put your x values down in your spreadsheet, I made mine go from -5 to 5. We chose this equation because finding it's derivative and antiderivative will be easy, so we can check our answer. It's the same equation shown in the picture below, which looks a lot nicer. To demonstrate, we're going to use the equation y=2x 3+6x 2-12x+4.
