The unit vector.
Plus 0 times the unit vector k.
And the unit vector for there is k.
That just says it's a unit vector.
Times the unit vector i plus dy/dt times dt.
Plus b dot u times our unit vector u.
Plus dy times the unit vector in the vertical direction.
And all of that times the k unit vector.
When something is a unit vector, instead of using this.
We're going to have that times my unit vector.
Times the unit vector k.
And then, all of that times our unit vector.
The vector 1, 0 dot the unit vector u, which is just u1, u2.
And that cap just means it's a unit vector.
Plus a sine of s times the k unit vector or the unit vector in the z direction.
That signifies that we're dealing with a unit vector.
These are unit vectors.
They're members of R3 and they're all unit vectors.
You know, maybe the unit vector is this long.
Let me draw it with a little hat to show that it is a unit vector.
You start with a unit vector there.
And the reason why they have this little hat here is because these are all unit vectors in R3.
I will put the vectors, or the unit vectors in this orange color.
Now, the two vectors that you're most familiar with to that span R2 are, if you take a little physics class, you have your i and j unit vectors.
I'm going to write the unit vectors up here.
If you want to find a unit vector-- or sometimes it's called a normalized vector-- that goes in the same direction as some vector v, you just figure out the length of v using the definition of vector length in Rn.
I showed you this in the unit vector video.
I need to take this dot my unit vector, let me write this down.
Plus b plus a cosine of s times cosine of t times the j unit vector-- the unit factor in the y direction.
But the bottom line, this vector right here-- if you add these scaled values of these two unit vectors, you're going to get r of a looking something like this. it's going to be a vector that looks something like that.
