And the unit vector for there is k.

And that cap just means it's a unit vector.

So this is i, that's the vector i, and then the vector j is the unit vector 0, 1.

It's a function of x and y, and it's equal to some scalar function of x and y times the i unit vector, or the horizontal unit vector, plus some other function, scalar function of x and y, times the vertical unit vector.

like, I could have written dx dt if I wanted to do, times the i unit vector, plus y prime of t, times the j unit vector.

We'll get dr is equal to x prime of t dt times the unit vector i plus y prime of t times the differential dt times the unit vector j.

And in our notation, i, the unit vector i that you learned in physics class, would be the vector 1, 0.

So if this is the unit vector in the x direction so that's i.

There's an upward vector on Unit 3 that Unit 1 doesn't have and that's an important clue we'll get to in a minute
