Dot my unit vector dot u1, u2.
I showed you this in the unit vector video.
Times the unit vector itself, so that we actually get a vector. .
We're going to have that times my unit vector.
The vector 1, 0 dot the unit vector u, which is just u1, u2.
What we can first do is convert v into a unit vector.
I need to take this dot my unit vector, let me write this down.
Let me draw it with a little hat to show that it is a unit vector.
The way you turn him into a unit vector, you figure out the magnitude.
So it's capital P of xy times the unit vector i.
We can convert v into a unit vector that goes in the same direction.
You say, hey Sal,how do we know if this is a unit vector or not.
Is the angular velocity of the unit vector eθ around the z axis of the cylinder.
Let's say someone gives you a vector v that isn't a unit vector.
That is equal to ca dot our unit vector u times unit vector u.
The unit vector is this, 1 over the square root of 5 times our vector v.
So I'm going to get u2 times my unit vector, u1, u2.
We can define a unit vector and let me pick a color, that I have not used yet.
If we assume that we're dealing with the unit vector definition for the line.
If the length of v was 1, or thisis another way of saying that, v is a unit vector.
So we have U1, which is a unit vector. It has length 1.
My unit vector, let's just assume that u can be rewritten as my unit vector is equal to sum u1 and u2.
You can define your u-- your unit vector could just be 1 over this, times that guy.
And in very general terms,it would be the x position as a function of time times the unit vector in the horizontal direction.
So its 5 squared of 3 times the unit vector. and what I like about this is that now I don't have to, tell you.
This is equal to, by our definition, we will use the unit vector version, because it's simpler.
You give me any unit vector and I will give you the transformation that gives you any projection of some other vector onto the line defined by that.
That's just how its defined and we also, unit vector tells us that its magnitude is one.
You can construct a unit vector that goes in the same direction as any vector, essentially just by dividing, or I guess multiplying, that vector times 1 over its length.
The projection of x onto L becomes x dot our unit vector, times the unit vector, times the unit vector itself.
