An imaginary number, when squared gives a negative result This is normally impossible (try squaring some numbers, remembering that multiplying negatives gives a positive, and see if you can get a negative result), but just imagine that you can do it! And we can have this special number (called i for imaginary): i2 = −1 Euler's formula states that for any real number x: e i x = cos ⁡ x + i sin ⁡ x , {\displaystyle e^{ix}=\cos x+i\sin x,} where e is the base of the natural logarithm , i is the imaginary unit , and cos and sin are the trigonometric functions cosine and sine respectively. The number e (e = 2.718), a.k.a. Euler's number, which occurs widely in mathematical analysis. The number i, the imaginary unit of the complex numbers.

Let's start with Euler's formula: eix = cos(x) + isin(x). In his Lectures on Physics, Richard Powers and Roots of a Complex Number. One of the applications of Euler's formula (equation 47) is 14 Mar 2018 Then there's 𝑖, which is an imaginary number.

He used i, an "imaginary number" to allow him to create a relationship between two quantities that one would normally not guess to be related to each other.

By definition, zero is considered to be both real and imaginary. The Imaginary Number At some point in your life, you've probably encountered the imaginary number, i. In case you haven't, i is defined as the square root of -1. In other words, it's a number so The Euler’s form of a complex number is important enough to deserve a separate section.
