ABC is an isosceles triangle and B= 90^{0}. If B and the midpoint P of AC are represented by 3+2i and 1-i then the other vertices are

In the Argand plane, the points represented by the complex numbers 2-i,-4+3i and -3-2i form

(a+2b)^{2}+(aω+2bω^{2})^{2}+(aω^{2}+2bω)^{2}=

The multiplicative inverse of (4+3i) is

The complex numbers sin x+ i cos 2x- i sin 2x are conjugate to each other for
