Complex Numbers Complex Numbers DEFINITION: Complex numbers are definited as expressions of the form a + ib where a, b ∈ R & i = . It is denoted by z i.e. z = a + ib. ‘a’ is called as real part of z (Re z) and ‘b’ is called as imaginary part of z (Im z). Every Complex Number Can Be Regarded As Purely real Purely imaginary Imaginary If b … [Read more...]
