                 **How to input your function:**
                 - Use `x` for the variable.
-                - Example: For \(x^2\), input `x**2`.
-                - For sine function, input `np.sin(x)`.
-                - For logarithm, input `np.log(x)`.
-                - For other mathematical operations, use `np` (e.g., `np.exp(x)`).
