I=- (I) 3 + 4 * 4 + 3 I equivalent to rotate for 90 degrees

Normally we can use the sine and cosine to set Angle, and can be used in complex plane program implemented?

CodePudding user response:

Abscissa as a real component, the vertical as the imaginary part, first calculate good rotation after the real part and imaginary part of, and then determine coordinates in the plane, from the original dotted lines in the past, in fact and the cartesian coordinate system have what difference
