So here we're going to explain how to solve a variety of problems that come in this following form.
00:07
We have the function, a position function, f of t, and it's written in some form, maybe 3t cubed minus 2t squared, or 3t cubed, f2p squared.
00:27
We'll look at something like this, for example.
00:30
And the first thing we want to do is graph the position function.
00:33
So we do that.
00:35
And then we want to graph the velocity function.
00:38
Well, that's going to be through taking the derivative, so our velocity function is going to be 9t squared minus 4t in this case.
00:45
But we know how to find the velocity function.
00:48
It's going to be f prime of t or f prime of x, and we're going to end up getting this.
00:53
So that's how we find velocity...
