Abstract
In this paper, we have developed a spreadsheet calculator for numerical differentiations. In this spreadsheet calculator, users may select either a given function or a given data to approximate the numerical differentiation. For a given function option, users are only required to key in the value of x, the functionflx) and the step size h. The spreadsheet calculator will then tabulate the (x, Ax)) data into a given table. On the other hand, for a given data option, users only have to key in the (x, y) data into the given table. For both options, the first derivative at the specified value of x will be approximated by using 2 point forward, 2point backward, 3point central, 3point forward, 3point backward and 5point formulas, whereas the second derivative at the specified value of x will be calculated by using 3point central and 5point formulas. With this numerical differentiations spreadsheet calculator, we hope to help educators to prepare their marking scheme easily and to assist students in checking their answers.
