Complex Numbers


   
 
Summary
 
If x and y are any real numbers, then x+iy is called a complex number.
 
In the complex number x+iy, the real numbers x and y are respectively called the real part and imaginary part of x+iy.
 
Two complex numbers are said to be equal if their real parts and imaginary parts are separately equal.
 
If a+ib and c+id are complex numbers, then
 
 
 
 
 
 
If z1 and z2 be any two complex numbers, then
 
 
 
 
 
 
 
 
 
If z1 and z2 be any two complex numbers, then
 
 
 
 
 
 
 
 
 
 
 
 
If x + iy is a complex number, then it is represented in the Argand plane by the point with coordinates (x,y).
