How can I know about quadrant in complex number/ in which quadrant they exists |
| Answer» Complex number can be represented as directed line from origin to a point in Argand plane which is similar to XY plane. Real part of complex number is potted on x axis and imaginary part on y axis. The length of directed line is equal to modulus of complex number where as angle made by directed line with x axis is called argument of complex number. If directed line lies in second quadrant means complex number lies in second quadrant.. In this way we can determine the quadrant of complex number.. | |
