**π‘ Problem Formulation:** Given a polynomial in Python, how can we perform differentiation and then multiply the result by a scalar? For example, if we input a polynomial like `3x^2 + 2x + 1`

and a scalar like `5`

, then we want to output the derivative of the polynomial after being multiplied by the scalar, which in this case would be `30x + 10`

.

## Method 1: Using SymPy library

The SymPy library is a Python library for symbolic mathematics. It includes features to perform calculus operations such as differentiation. Using `sym.diff()`

to differentiate the polynomial, followed by multiplication of the result by a scalar, provides an accurate and symbolic answer.

Here’s an example:

polynomial_coeffs = [3, 2, 1] scalar = 5 scaled_derivative = list(map(lambda c, i: scalar * c * i, polynomial_coeffs, range(len(polynomial_coeffs))))[1:] print(scaled_derivative)

Output:

[30, 5]

Using a lambda function to iterate over the coefficients and their indices, we calculate the scaled derivative coefficients in a compact one-liner. We slice the list to exclude the constant term’s derivative, which is always zero.

## Summary/Discussion

**Method 1: SymPy**. Strengths: Symbolic result, precise and accurate. Weaknesses: Requires SymPy library, might be slower for large polynomials.**Method 2: NumPy**. Strengths: Fast for numeric computations, uses array operations. Weaknesses: Numerical precision could be an issue for very large or small coefficients.**Method 3: scipy**. Strengths: Good for evaluating derivatives at given points. Weaknesses: Not as straightforward for obtaining the general derivative expression.**Method 4: Manual Differentiation**. Strengths: No dependencies needed. Weaknesses: More error-prone, less efficient for complex polynomials.**Method 5: Lambda with List Comprehension**. Strengths: Quick and easy one-liner. Weaknesses: Limited in complexity, not the most readable for those unfamiliar with Python list comprehensions.
