WebFor example, 3 i , i 5 , and − 12 i are all examples of pure imaginary numbers, or numbers of the form b i , where b is a nonzero real number. Taking the squares of these numbers sheds some light on how they relate to the real numbers. Let's investigate this by squaring the number 3 i .

WebThis answer is not correct. You have to use Euler's formula. i^i = {e^i (2kpi+pi/2)}^i = e^i^2 (2kpi+pi/2) = e^- (2kpi+pi/2) where k is an element of the set of integers. The principle value for k=0 = e^-pi/2 = 0.207879576350761908546955465465465. 1 comment. ( 7 votes) Upvote. Downvote. Flag. Show more...

Imaginary unit - Wikipedia
https://en.wikipedia.org/wiki/Imaginary_unit
WebThe imaginary unit or unit imaginary number ( i) is a solution to the quadratic equation x2 + 1 = 0. Although there is no real number with this property, i can be used to extend the real numbers to what are called complex numbers, using addition and multiplication. A simple example of the use of i in a complex number is 2 + 3i.

WebBibliography. External links. Imaginary number. An imaginary number is a real number multiplied by the imaginary unit i, [note 1] which is defined by its property i2 = −1. [1] [2] The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25. The number zero is considered to be both real and imaginary.

WebThey are also defined as the square root of negative numbers. An imaginary number is the product of a non-zero real number and the imaginary unit "i" (which is also known as "iota"), where i = √ (-1) (or) i 2 = -1. Let's try squaring some real numbers: (−2) 2 = −2×−2 = 4. 5 2 = 5×5 = 25. (1.3) 2 = 1.3×1.3 = 1.69.
