* * * York complex number, where two real parts are equal and imaginary parts are opposite, is * * * York complex number. When the imaginary part is not zero, the complex number of yoke means that the real part is equal and the imaginary part is opposite. If the Ruo Xu part is zero, its * * * yoke complex number is itself (also called * * * yoke imaginary number when the imaginary part is not equal to 0).

The * * * yoke of the complex number z is marked as z (with a horizontal line on it), and sometimes it can be expressed as Z*. At the same time, the complex number Z (plus a horizontal line) is called the complex yoke of the complex number Z.

* * * The point corresponding to the complex number of the yoke is symmetrical about the real axis. Two complex numbers: x+yi and x-yi are called * * * yoke complex numbers. Their real parts are equal, but their imaginary parts are opposite. On the complex plane, the points representing the complex numbers of two yokes are symmetrical about X, which is the origin of the word "* * * yoke".

Two cows pull a plow in parallel with a beam on their shoulders. This beam is called a "yoke". If x+yi is represented by z, then adding a "one" to z is x-yi, and vice versa.

The importance of learn mathematics:

1. Mathematics is closely related to our life. To say that the real effect of learning mathematics is not reflected in exam-oriented education, but in my own thinking about the future.

2. The importance of mathematics is self-evident. Mathematics is the foundation of all sciences and an important channel to cultivate logical thinking. It can be said that every major progress of our mankind is strongly supported by mathematics.

3. The application of mathematical knowledge in life is everywhere. From the calculation of daily living costs, to astronomy, geography, quality control, agricultural economy, aerospace, there are shadows of using mathematics.
