In this mathcast, we are looking to find the math behind
a ship sailing from port A up to port B.
So let us stop the animation for a moment and move to t back to 0 and we can see that the bottom left-
hand corner of the ship image is now at point A.
If we move t up to 1, we see that the bottom left-hand
corner is now at point B.
And we saw that the ship was sailing at a constant
speed from port A to port B.
How about when t=1/2=0.5? We can see that the bottom
left-hand corner is halfway between A and B. So it is at
the midpoint.
How can make that into a math formula that will animate
our ship?
