If (a1+ib1)( (a2+ib2)…. (an+ibn)= A+iB, then (a12 +b12)( a22 +b22 )….(an2 +bn2)=
If z1=1+2i,z2=2+3i,z3=3+4i,then z1,z2 and z3 represents the vertices of
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
