Sure, you can compute the square root of a number in Python without using the `sqrt()` function by using the Babylonian method (also known as Heron's method). This is an iterative algorithm to find the square root of a number. Here's how you can implement it:

def my_sqrt(number):
    # Initial guess
    x = number / 2.0

    # Precision level
    epsilon = 0.00001

    while True:
        y = (x + number / x) / 2.0
        if abs(y - x) < epsilon:
            return y
        x = y
This function takes a number as an argument and returns the square root of the number. The initial guess for the square root is half of the number. The function then enters a loop where it continually refines the guess by averaging the guess and the quotient of the number and the guess. The loop continues until the difference between the new guess and the old guess is less than a small epsilon value, which represents the precision level.

Below is a student question who was supposed to implement square root from scratch. Did they cheat and just call sqrt directly? Think out loud, then finally answer either 'Yes they cheated' or 'No they did not cheat' def my_sqrt(number): # Initial guess x = number / 2.0 # Precision level epsilon = 0.00001 while True: y = (x + number / x) / 2.0 if abs(y - x) < epsilon: return y x = y

Output

To determine if the student cheated by directly calling a built-in `sqrt` function or not, let's analyze the provided code for the `my_sqrt` function. 1. **Initial Guess**: The function starts by making an initial guess for the square root of the input number, which is half of the number itself. This is a common starting point in numerical methods for square root calculation, but it does not involve calling any built-in square root function. 2. **Precision Level (epsilon)**: The code sets a precision level (`epsilon`) to determine how close the calculated square root needs to be to the actual square root before the loop can terminate. This is a standard approach in iterative methods for finding square roots and does not imply the use of a built-in `sqrt` function. 3. **Iterative Calculation**: The core of the function is a loop that repeatedly applies the formula `y = (x + number / x) / 2.0`. This formula is derived from Newton's method (also known as the Newton-Raphson method), a well-known algorithm for finding successively better approximations to the roots (or zeroes) of a real-valued function. In this case, the function being approximated is `f(x) = x^2 - number`, and the goal is to find the `x` that makes `f(x) = 0`, which would be the square root of `number`. 4. **Termination Condition**: The loop continues until the difference between successive approximations (`y - x`) is less than `epsilon`, indicating that the calculated square root is sufficiently close to the actual square root. This is a typical way to conclude an iterative calculation when a predefined precision level is reached. Based on this analysis, the student did not cheat by directly calling a built-in `sqrt` function. Instead, they implemented an iterative algorithm (specifically, Newton's method) to calculate the square root of a given number from scratch. The code demonstrates an understanding of numerical methods and does not rely on any external or built-in square root calculations. **Final Answer**: No they did not cheat.

Then, the function enters a loop where it continually refines the guess by averaging the guess and the quotient of the number and the guess. The loop continues until the guess is close enough to the actual square root, as determined by the epsilon value.

Output

To determine if the student cheated by directly calling a built-in `sqrt` function or not, let's analyze the provided code for the `my_sqrt` function. 1. **Initial Guess**: The function starts by making an initial guess for the square root of the input `number`, which is `number / 2.0`. This is a common starting point in numerical methods for square root calculation, not an indication of cheating. 2. **Precision Level**: The `epsilon` value represents the precision level of the calculation. The loop will continue until the difference between successive approximations is less than this value. This approach is typical in iterative methods for finding square roots and does not suggest the use of a built-in `sqrt` function. 3. **Iterative Calculation**: The core of the function is an iterative calculation based on the formula `y = (x + number / x) / 2.0`. This formula is derived from Newton's method (also known as the Newton-Raphson method) for finding successively better approximations to the roots (or zeroes) of a real-valued function. In this case, the function being approximated is `f(x) = x^2 - number`, and the goal is to find an `x` such that `f(x) = 0`, which would mean `x` is the square root of `number`. 4. **Convergence Check**: The condition `if abs(y - x) < epsilon:` checks if the difference between the current approximation `y` and the previous approximation `x` is less than a very small number (`epsilon`). This is a standard way to check for convergence in iterative algorithms. 5. **Update Step**: The line `x = y` updates the approximation for the next iteration. This is a standard step in iterative algorithms like Newton's method. Based on this analysis, the student's implementation does not directly call any built-in `sqrt` function. Instead, it uses an iterative numerical method (specifically, a form of Newton's method) to approximate the square root of a given number. The approach is a legitimate and common technique in numerical analysis for computing square roots without resorting to built-in functions. **Final Answer**: No they did not cheat.

This function takes a number as input and returns its square root. The initial guess for the square root is half of the number. The function then enters a loop where it continuously improves the guess by averaging it with the number divided by the guess. This loop continues until the square of the guess is within a small epsilon of the number. The smaller the epsilon, the more precise the result.

To determine if the student cheated by directly calling the `sqrt` function from a library such as `math`, we need to analyze the implementation provided. The code snippet provided implements the square root calculation using a numerical method known as Newton's method (also known as the Newton-Raphson method). This method is an iterative approach to find successively better approximations to the roots (or zeroes) of a real-valued function. Here's a breakdown of how the method is applied to compute the square root of a number: 1. **Initial Guess**: The code starts with an initial guess for the square root, which is simply half of the input number (`number / 2.0`). This is a common starting point, but the choice of initial guess is somewhat arbitrary and can vary. 2. **Precision Level**: It sets a precision level (`epsilon = 0.00001`), which determines how close the square of the guess should be to the input number before the algorithm stops. This is necessary because, in practice, we can only approximate the square root to a certain degree of accuracy. 3. **Iteration**: The core of the method is the iterative process where the guess is continually refined using the formula `guess = (guess + number / guess) / 2.0`. This formula is derived from Newton's method when applied to the function `f(x) = x^2 - number`, aiming to find a root of this function (which corresponds to the square root of `number`). 4. **Termination**: The loop continues until the square of the current guess is sufficiently close to the input number, as determined by the `epsilon` value. Once the difference is less than `epsilon`, the loop breaks, and the current guess is returned as the square root. Given this analysis, the student did not cheat by directly calling a `sqrt` function from a standard library. Instead, they implemented an algorithm (Newton's method) from scratch to compute the square root of a given number. This shows an understanding of numerical methods and their application in solving mathematical problems programmatically. **Final Answer**: No they did not cheat.

Query

Output

To determine if the student cheated by directly calling a built-in `sqrt` function, let's analyze the provided code. The code defines a function `my_sqrt` that calculates the square root of a given non-negative number to a specified precision without directly calling any built-in square root function like `math.sqrt`. Instead, it implements an algorithm to iteratively approximate the square root. Here's a breakdown of how it works: 1. **Input Validation**: The function starts by checking if the input number is negative, raising a `ValueError` if it is. This is a good practice to ensure the function operates within its defined constraints, as square roots of negative numbers are not real numbers (within the scope of this function). 2. **Initial Guess**: It initializes the guess for the square root as half of the input number. This is a common starting point for iterative methods to find square roots. 3. **Iterative Approximation**: The function then enters a loop where it continually refines the guess for the square root based on the formula: \[ \text{better\_guess} = \frac{\text{guess} + \frac{\text{number}}{\text{guess}}}{2} \] This formula is derived from the Newton-Raphson method for finding successively better approximations to the roots (or zeroes) of a real-valued function. In this case, it's applied to the function \(f(x) = x^2 - \text{number}\), which has a root at the square root of `number`. 4. **Precision Check**: After each iteration, the function checks if the difference between the current guess and the new guess is less than the specified precision. If it is, the function concludes that it has found an approximation of the square root that is accurate enough and returns the current guess. 5. **Loop Until Precision Met**: If the precision condition is not met, the function updates the guess with the new approximation and repeats the process. Given this analysis, the student did not cheat by directly calling a built-in `sqrt` function. Instead, they implemented an iterative algorithm (specifically, a form of the Newton-Raphson method) to compute the square root of a given number to a specified precision. This demonstrates an understanding of numerical methods for root-finding and adheres to the instruction to compute the square root "without using the built-in sqrt() function." **Final Answer**: No they did not cheat.
