Express (2+3i/ 2-3i)-(2-3i/ 2+3i) in the form of a+ib
The equation of the line joining the points represented by 2-3i and -3+4i in the Argand plane is
ABC is an isosceles triangle and B= 900. 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+2bω2)2+(aω2+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
The modules of (3+2i)(2-i)/ (1+i) is
If the roots of (z - 1)n = i(z + 1)n are plotted in the argand diagram they are:
If three complex numbers are in A.P. then they lie on
