Describe a minimal set of base cases that would make this a well-defined recurrence. We call (i, j) a base case if it is not in [0, m] × [0, n]. Set the value of S for each base case to be 0. Make sure to only include the base cases that are necessary.

An observer(o) spots a plane(p) taking off from a local airport and flying at a 29 degree angle horizontal to her line of sight and located directly above a tower(t). the observer also notices a bird circling directly above her. if the distance from the plane(p) to the tower(t) is 6,000ft., how far is the bird(b) from the plane(p).
