- f(0) is the function evaluated at x = 0
- f'(0) is the first derivative of f(x) evaluated at x = 0
- f”(0) is the second derivative of f(x) evaluated at x = 0
- … and so on
Step 3: Dive into Derivatives
To calculate the Maclaurin series, we need to evaluate the function and its derivatives at x = 0. This can be a bit tricky, especially for complex functions. Don’t worry; we’ll tackle strategies for handling these challenges later.
