Very good! That's how simple vector components are.

Let us say that a vector \(\vec{A}\) has an x-component of 5 and a y-component of 7. We can write this as \(A_x = 5, A_y = 7\). We can also write this as
\(\vec{A} = 5 \hat\imath + 7 \hat\jmath\). The \(\hat\imath\) means that the number multiplying it is the x-component and the \(\hat\jmath\) means that the number multiplying it is the y-component. In the next module, you will see why this notation is useful.
