Supported Expressions

This calculator supports multiple types of imaginary number formats:

1. Powers of i

The calculator simplifies powers using the repeating cycle:

  • i¹ = i
  • i² = -1
  • i³ = -i
  • i⁴ = 1

Example:

  • Input: i^7
  • Output: i

2. Square Roots of Negative Numbers

The tool automatically converts negative square roots into imaginary form.

Example:

  • Input: sqrt(-16)
  • Output: 4i

3. Basic Complex Numbers

You can also enter expressions like:

  • 3+4i
  • 5-2i

The calculator will return them in simplified form.


4. Simple Imaginary Unit

If you enter:

  • Input: i
  • Output: i

Real-Life Example of Using the Calculator

Let’s take a practical example to understand how this tool works.

Example 1: Power of i

Input:
i^10

Step-by-step concept:
The powers of i repeat every 4 cycles:

  • i¹ = i
  • i² = -1
  • i³ = -i
  • i⁴ = 1

Now:

  • 10 ÷ 4 = remainder 2
  • i² = -1

Output:
-1


Example 2: Square Root of Negative Number

Input:
sqrt(-25)

Calculation:
√25 = 5, so:

Output:
5i


Example 3: Complex Number

Input:
3+4i

Output:
3+4i
