Complex Numbers

A number of the form a + ib, where a and b are real numbers and , is defined as a complex number. For the complex numbers z = a + ib, a is called the real part (denoted by Re z) and b is called the imaginary part (denoted by Im z) of the complex number z.

Example: For the complex number , Re  and Im  

Two complex numbers z1 = a + ib and z2 = c + id are equal if a = c …
