How To Calculate Derivative In Excel

Mastering the calculation of derivatives in Excel is essential for professionals and students dealing with mathematical, financial, or engineering data analysis. Excel provides built-in functions and formulas that can be used to compute the rate of change or slope of a curve represented by data points.

However, for a more intuitive and efficient experience, we'll explore why Sourcetable offers a simpler alternative for derivative calculations compared to the traditional methods in Excel.

How to Calculate Derivative in Excel

Using the DERIVF Function

The Excel function =DERIVF computes numerical derivatives, either first or higher order. It uses a highly accurate and adaptive algorithm, suitable for various mathematical functions.

Understanding DERIVF Syntax

The syntax for the DERIVF function is =DERIVF(f, x, p, [n]). Here, f is the function formula, x is the variable of differentiation, p is the point for computing the derivative, and n (optional) specifies the derivative order, defaulting to 1.

Adaptive Algorithm and Ridders' Method

DERIVF leverages Ridders' method, an adaptive algorithm that provides high precision by driving the step size to zero using polynomial extrapolation. Ridders' method incorporates Neville's algorithm for increased accuracy.

Setting the Starting Step Size

An important parameter for Ridders' method is the initial step size, which should align with the function's behavior around the differentiation point. Use the INITSTEP option to set this starting step size.

Computing Partial Derivatives

DERIVF can compute partial derivatives of any order by nesting the function. It adapts to the function's range and provides precise results, thanks to the underlying algorithms and step size optimization.
