00:00:01.060 --> 00:00:16.370
The components of the vector 𝐮 are two, negative one as the terminal point of the vector is two units right of the initial point and negative one units up or one unit down from the initial point.
00:00:17.390 --> 00:00:20.280
What are the components of the vector 𝐯?
00:00:21.760 --> 00:00:26.420
Any vector in two dimensions has an 𝑥- and 𝑦-component.
00:00:27.370 --> 00:00:34.230
These tell us how we move from the initial or start point to the end or terminal point.
00:00:35.170 --> 00:00:44.620
The 𝑥-component has a positive value if we are moving to the right, and the 𝑦-component has a positive value if we are moving upwards.
00:00:45.660 --> 00:00:52.760
Vector 𝐮 is equal to two, negative one as we move two units to the right and one unit down.
00:00:54.080 --> 00:01:03.440
In vector 𝐯, we move four units to the right and two units down to get from the initial point to the terminal point of the vector.
00:01:04.280 --> 00:01:11.910
This means that vector 𝐯 has an 𝑥-component equal to four and a 𝑦-component equal to negative two.
00:01:13.020 --> 00:01:16.220
Vector 𝐯 is equal to four, negative two.
