JEE Advance - Mathematics (2007 - No. 27)
A man walks a distance of 3 units from the origin towards the north-east ($$N\,{45^ \circ E }$$) direction. From there, he walks a distance of 4 units towards the north-west $$\left( {N\,{{45}^ \circ }\,W} \right)$$ direction to reach a point P. Then the position of P in the Argand plane is
$$3{e^{i\pi /4}} + 4i$$
$$\left( {3 - 4i} \right){e^{i\pi /4}}$$
$$\left( {4 + 3i} \right){e^{i\pi /4}}$$
$$\left( {3 + 4i} \right){e^{i\pi /4}}$$
