Question 2: Derivation Problem

Difficulty: ⭐⭐⭐

Question: Derive the following expression:

$$\frac{\partial}{\partial x} f(x) = ?$$

Given that $f(x) = x^2 + 2x + 1$.

Hint: Use the power rule.

---

Solution

Step 1: Apply the derivative

$$\frac{d}{dx}(x^2) = 2x$$

Step 2: Continue with each term

$$\frac{d}{dx}(2x) = 2$$$$\frac{d}{dx}(1) = 0$$

Step 3: Combine

$$\frac{\partial f}{\partial x} = 2x + 2$$

Final Answer:

$$\boxed{\frac{\partial f}{\partial x} = 2x + 2}$$

Question 3: Implementation Challenge

Difficulty: ⭐⭐⭐

Question: Implement the following function:

def function_name(param1, param2):
    """
    Description of what this function should do.

    Args:
        param1 (type): Description
        param2 (type): Description

    Returns:
        type: Description of return value
    """
    # YOUR CODE HERE
    pass

---

Solution

def function_name(param1, param2):
    """
    Description of what this function does.

    Args:
        param1 (type): Description
        param2 (type): Description

    Returns:
        type: Description of return value
    """
    # Step 1: Initialize variables
    result = 0

    # Step 2: Process input
    for item in param1:
        result += item * param2

    # Step 3: Return result
    return result


# Test the implementation
if __name__ == "__main__":
    test_input = [1, 2, 3]
    test_param = 2

    output = function_name(test_input, test_param)
    print(f"Result: {output}")  # Expected: 12
