To approximate it with out spreadsheet, we just write (in any cell) "=F81-F31". We know that, in general, velocity is related to acceleration by the following equation: So, to calculate the velocity at any given time, we need to calculate the integral of acceleration through time. For example, in the sample workbook, we had the function y = 4*x^2; we knew 10 points, so we applied the formula 9 times. This function is going to have three arguments: an initial position (x0), a starting time (t1), and an ending time (t2).For complex functions like this, it's helpful to create a skeleton of what the function will do using comments. Francesco With optional arguments, you can override the default integration algorithm as well as supply singular points for the integrand f (x) if applicable. It is easy to find mistakes in your calculations when you can see every step of the process. You need to increase the power of each x value by 1 and divide it by the increased power value. Click on the cell below "Integral", and type in "=SUM (", and do not exit the cell.
