What does my math mean?
The imaginary unit stipulates that i=- 1, and I can perform four operations with real numbers according to the same algorithm. I is called the imaginary unit. The power of the imaginary unit I is periodic, and the imaginary unit is represented by I. Mathematically, the imaginary number is a+b*i number, where A and B are real numbers, b≠0, and i=- 1. The word imaginary number was founded by Descartes, a famous mathematician in the17th century.

Imaginary unit

Rule one? =- 1, and I can use real numbers to perform four operations according to the same algorithm, and I is called imaginary unit. The power of the imaginary unit I is periodic, and the imaginary unit is represented by i.

The power of the imaginary unit I is periodic, and the imaginary unit is represented by I. In mathematics, the imaginary number is a number in the form of a+b*i, where A and B are real numbers, b≠0, I? =- 1。 The word imaginary number was founded by Descartes, a famous mathematician in the17th century, because the concept at that time thought it was a non-existent real number. Later, it was found that the real part A of the imaginary number a+b*i can correspond to the horizontal axis and the imaginary part B can correspond to the vertical axis on the plane, so that the imaginary number a+b*i can correspond to the points (a, b) on the plane.
