个新的距离公式复平面与直角坐标平面是很好地对应着的．复平面内的复数ｘ＋ｙｉ，对应于直角坐标平面内的点（ｘ，ｙ），显然，它们之间是一一对应的．于是，自然会发问：复平面内也有距离公式吗？复平面内的曲线也有方程吗？Ｔ：在复平面内，若点Ｚ１、Ｚ２分别对应于复... The new distance formula complex plane corresponds well with the Cartesian coordinate plane. The complex number x + yi in the complex plane corresponds to the point (x, y) in the rectangular coordinate plane. Obviously, there is a one-to-one correspondence between them. So, naturally, I would ask: Is there a distance formula in the complex plane? Is there an equation for the curve in the complex plane? T: in the complex plane, if the points Z1, Z2 correspond to the complex ...
