The unit vector.
Plus, 4 times the unit vector j.
If unit vectors are defined such that.
It's a unit vector.
And that is equal to, 2i, so two times the unit vector i.
Times unit vector i.
So it's just 5 times the unit vector j.
Is the unit vector in direction.
So we define these unit vectors.
With uR a unit vector in the radial direction.
So what we have done now,by defining these unit vectors--.
This is the unit vector i.
But when we write things as multiples of the unit vectors.
Let me draw the unit vector up here.
Its x componentcan be written as a multiple of the x unit vector.
And then all of that times the unit vector in the i direction.
Well, the unit vector i goes in the exact same direction.
And so what we do is we introduce the ideas of, or the idea of unit vectors.
We can define a unit vector and let me pick a color, that I have not used yet.
We really should call it, we really should call it,five square roots of 3 times this unit vector.
That's just how its defined and we also, unit vector tells us that its magnitude is one.
Instead of drawing it,a very easy representation is exactly what we did up here, a unit vector notation.
So it's 5 times 10 times 1/2 times the unit vector, so that equals 25 times the unit vector.
We can write v sub x is equal to 10 cosine of 30 degrees times--that's the degrees--times the unit vector i--.
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.
Let's call a first vector a and, I don't know, let's make it interesting, let me say it's minus 3 times the unit vector i plus2 times the unit vector j.
The direction is completely specified by this unit vector, and a unit vector is just a vector of magnitude 1 that's pointing in some direction.
So say I had vector a and that equals 2 times the unit vector i plus3 times the unit vector j.
Provided not all κX are equal, there is some unit vector X1 for which k1= κX1 is as large as possible, and another unit vector X2 for which k2= κX2 is as small as possible.
In the last video I said, well, the whole reason why this unit vector notation is even-- Well, one of the reasons, we will see that there many reasons why it's useful.
