Square root of -1


Understanding the concept of the square root of -1, often represented as i, is crucial in the realm of complex numbers and mathematical calculations. Although HTML is primarily used for web development and content creation, let’s explore how one can express the square root of -1 within an HTML context.

The Imaginary Unit (i)

An imaginary unit, commonly denoted as i, is a mathematical construct introduced to represent the square root of -1. In HTML, we can display this symbol using the appropriate HTML entity code: &i; or i. Here’s an example:

<p>The square root of -1 is denoted as &i; or &#x69;.</p>

Complex Numbers

Complex numbers encompass both real and imaginary components. They are typically written in the form a + bi, where a represents the real part and b represents the imaginary part. HTML provides the capability to represent complex numbers using appropriate mathematical notations, including subscripts and superscripts:

<p>A complex number can be written in the form <strong><i>a + bi</i></strong>, where <strong>a</strong> is the real part and <strong>b</strong> is the imaginary part.</p>

The Euler’s Identity

Euler’s identity is a fundamental equation connecting several key constants in mathematics: e, π, i, and 1. This remarkable formula is expressed as:

<p>e + 1 = 0</p>

Euler’s identity signifies the profound relationship between exponential, trigonometric, and imaginary functions. Implementing the equation within an HTML context can be done by using the appropriate HTML tags for superscript and subscript:

<p>The equation <strong>e</strong><sup>i</sup><strong>π</strong> + 1 = 0 signifies the interplay between exponential, trigonometric, and imaginary functions.</p>


The square root of -1, represented as i, plays a significant role in the field of complex numbers and various mathematical equations. By using appropriate HTML codes and tags, we can effectively convey and visualize the concept of the imaginary unit within HTML documents.
