WebSep 16, 2024 · To find e^x using the recursive function, we need to use static variables. A function can return only one value, and when we need to include multiple values in a recursive function, we use static variables. The Taylor Series is a combination of multiple values like sum, power and factorial term, hence we will use static variables.
