 # Complex Numbers Class 11

Complex Numbers Class 11 – A number that can be represented in form p + iq is defined as a complex number. [Where, p and q are real numbers and $i=\sqrt{-1}$]. For a complex number z = p + iq, p is known as the real part, represented by Re z and q is known as the imaginary part represented by Im z of complex number z. ### Complex Numbers Class 11 Concepts
