At one instant ,ships X and y are at a distance of d from each other.THe velocities of ship x and ship y are u and v respectively. Angle a and b are acute. Find the tangent of angle betweeen the direction of relative velocity and
the relative velocity vector is
relative displacement vector, xRy=(-d)i
Before i proceed with the dot product formulas, can i confirm whether the above is crrect?

According to your figure,
Velocity of x relative to y=velocity of x relative to earth-velocity of y relative to earth=
Displacement of x relative to y =
Hope this helps.
