Solve Kinematics Problem: Man Swims Across River

Click For Summary
The discussion focuses on a kinematics problem involving a man swimming across a river with a current flowing along the positive X-axis. The man starts from the origin and aims to reach the point (0, l) on the opposite bank, where l is the river's width. Participants are prompted to derive the equation of the path he follows, considering his swimming velocity and the river's current. There is a reminder that the forum is not intended for direct problem-solving assistance. Adhering to forum rules is emphasized for effective participation.

consider a river flowing with a speed u along positive X axis . a man starts swimming from a point on the bank of the river ( which is considered to be as origin ) . l is the width of the river and the velocity of man is always directed towards the point (0,l) . find the equation of the path that the man follows ?

(a) The polarisation pattern is elliptical with maximum (1,1) and minimum (-1,-1), and anticlockwise in direction. (b) I know the solution is a quarter-wave plate oriented π/4, and half-wave plate at π/16, but don't understand how to reach there. I've obtained the polarisation vector (cos π/8, isin π/8) so far. I can't find much online guidance or textbook material working through this topic, so I'd appreciate any help I can get. Also, if anyone could let me know where I can get more...
