For the previous example we arrived at the result
x(t)
= 1.06t - 3.18 cm
and
y(t)
= 0.44t + 1.70 cm
In vector notation, this result reads
r(t)
= x(t)i
+ y(t)j
= (1.06t-3.18)i
+ (0.44t+1.70)j
cm
Sometimes we will use the following column notation
The x component
comes upstairs,
whereas the y component
comes downstairs.
