Hi.

In this problem, we're given that we have a plane that is directly above denver, colorado, and it's flying to bismarck, dakota.

Hi, in this problem, we're given that a plane flies directly above denver, colorado, and it's flying to bismarck, north dakota.
00:25
And so we're given some data about it.
00:28
The important thing, first off, is that bismarck is 6 ,000.
00:33
Degrees north of east from denver, and the plane is traveling directly on this line.
00:39
So if we have denver here, then bismarck will be here.
00:54
And this angle is going to be 60 degrees, and the plane is flying directly in this direction.
01:01
Now denver, we're assuming, is at the origin zero -zero.
01:05
So we want to come up with the position function of the plane in kilometers and in hours...
