Calculating Cubic Root of Negative Numbers in Python – Simple Guide Comparison Blog
The cubic root of a number is finding a number that when multiplied by itself thrice (i.e., raised to the power of three), gives the original number. Usually, we find the cubic root of positive numbers, but it’s also possible to find the cubic roots of negative numbers in Python. This article will discuss four different methods to calculate the cubic root of negative numbers in Python along with their pros and cons.
Method 1: Using Complex Numbers
This method uses Python’s built-in complex number support. A complex number is made up of a real part and an imaginary part. We can represent cubic roots of negative numbers using complex numbers, where the real part is zero. To find the cubic root of a negative number, we take its absolute value, find the cubic root of that, and multiply it by i (the imaginary unit). For example, to find the cubic root of -8:
|Using Complex Numbers
|– Built-in support for complex numbers in Python.
|– Complex arithmetic can be harder to understand.
|Using Math.pow and math.sqrt Functions
|– Built-in support for math functions in Python.
|– Less efficient than other methods.
|Using Newton-Raphson Method
|– Faster and more accurate than some other methods.
|– Algorithmic complexity can be higher.
|Using Scipy Library
|– The fastest and most accurate method.
|– Requires installation of external library.
Method 2: Using Math.pow and math.sqrt Functions
In this method, we use the pow function for raising a number to a given power and the sqrt function to find the square root. We can represent the cubic root of a negative number as a positive real part multiplied by -1. To find the cubic root of -8:
Method 3: Using Newton-Raphson Method
The Newton-Raphson Method is a numerical method for finding the roots of an equation. In this method, we start with an initial guess and refine it using the function value and its derivative. The formula for finding the cubic root using the Newton-Raphson Method is:
Method 4: Using Scipy Library
The Scipy library is a collection of mathematical algorithms and functions built on top of the Numpy library. It includes functions for numerical integration, optimization, interpolation, signal processing, linear algebra, etc. We can use the scipy.special.cbrt function to find the cubic root of a number.
When it comes to finding the cubic root of a negative number in Python, there are multiple methods available. Each method has its pros and cons in terms of efficiency, ease, and accuracy. Selecting the appropriate method depends on the specific requirements of the application at hand. Hopefully, this comparison blog article has provided some useful insights.

People also ask about calculating cubic root of negative numbers in Python:
- What is the cubic root of a negative number?
- How do I calculate the cubic root of a negative number in Python?
- Can I calculate the cubic root of a negative number without using the cmath module?
- What is the format of the output when calculating the cubic root of a negative number in Python?
The cubic root of a negative number is a complex number, which has both a real and imaginary part.
You can use the cmath module in Python to calculate the cubic root of a negative number. Here’s an example:
“`python import cmath num = -8 cubic_root = cmath.pow(num, 1/3) print(cubic_root) # Output: (1.0000000000000002+1.7320508075688772j) “`
No, you cannot calculate the cubic root of a negative number without using the cmath module as it involves complex numbers.
The format of the output is a complex number, which has both a real and imaginary part. It is represented in the form of a + bj, where a and b are real numbers and j is the square root of -1.
