The vector represented by the complex number 2 – i is rotated about – InterviewSolution

1.	The vector represented by the complex number 2 – i is rotated about the origin through an angle π2 in the clockwise direction, the new position of point is(a) 1 + 2i(b) –1 –2i(c) 2 + i(d) –1 + 2i
Answer» The vector represented by the complex number 2 – i is rotated about the origin through an angle $\frac{π}{2}$ in the clockwise direction, the new position of point is (a) 1 + 2i (b) –1 –2i (c) 2 + i (d) –1 + 2i
