The complex number `z=(1+i)` represented by the point `P` is Argand plane and OP is rotated an angle of `(pi)/(2)` in counter clock wise direction then the resulting complex number is

If magnitude of a complex number 4 – 3i is tripled and is rotated by an angle pi anticlockwise then resulting complex number would be

The point represented by the complex number 2-i is rotated about origin through on angle pi/2 the clockwise direction, the new position of the point is

The complex number z=1+i is rotated through an angle (3 pi)/(2) in anti-clockwise direction about the origin and stretched by aditional sqrt(2) unit,then the new complex number is:

The point represented by the complex number (2 - i) is rotated about origin through an angle (pi)/(2) in the clockwise direction, the new position of point is (A) 1+2i (B) -1-2i (C) 2+i (D) -1+2i

The point represented by the complex number 2+i rotated about the origin through an angle (pi)/(2) . The new position of the point is

Let the point P represent the complex number z. If OP is turned round 0 by an angle pi/2 in the clockwise sense where 0 is the origin then in the new position P represents the complex number _______.

write the complex numbers that are represented by the following points in the complex plane (i) 0,3 (ii) (-1 ,0)

Show that complex numbers z_1=-1+5i and z_2=-3+2i on the argand plane.
