Prove that 2 complex numbers a+ib and c +id are equal if a =c and b=d.
Two complex numbers are equal if the real and imaginary parts of both the complex numbers are equal.
Consider two real numbers, a + ib and c + id.
They are equal if real parts a = c and imaginary parts b = d.
But this is not valid in the case of real numbers.
As, 2 + 3 = 4 + 1 does not mean, 2 = 3 and 4 = 1.
