Hello y 'all.
00:02
I hope you're doing well today.
00:04
I'm himani, and we're going to be talking about some vectors.
00:08
Okay, so we're asked to calculate u plus v and u minus v, and then represent each result graphically, and we're given u and v, so let's go ahead and write down what u and v are.
00:19
So u is equal to negative 5 negative 1 and v is equal to 4 3.
00:40
Oh and of course these should have these should have triangular brackets which is my bad just like that.
00:54
Okay, so let's go ahead and calculate u plus v in place.
01:02
And the way that we do that is we just add up the x's and the y is like that.
01:09
So u plus v will be equal to negative 5 plus 4, which is negative 1.
01:16
And then for the y component, it'll be negative 1 plus 3, which is 2.
01:23
So u plus v is 1 2, negative 1 2, sorry.
01:28
And then to find u minus v, what we have to do is subtract the x's and the y's...
