Two ships A and B are moving with constant speeds Va and Vb along straight intersecting courses. The navigator of ship B notes the time rates fo change of the separation distance r between the ships and the bearing angle theta. Show the second derivative of theta =-2(dr/dt*dtheta/dt)/r and d^2r/dt^2= r*(dtheta/dt)^2
