In this problem two vectors a equals to 2x plus y and b equals to x plus 3y are given.
00:10
Here a and b are vectors, x, y are unit vectors, a, b are magnitude of vectors.
00:20
So draw the vectors on cartesian coordinate system.
00:25
So there are few things asked to us.
00:29
So we will solve for it.
00:30
So here how do we solve this? so let us see.
00:36
A here is vector a is here given 2x cap plus y cap.
00:44
Right? can we write it in this way? yes in vector form.
00:49
So this will be b.
00:51
Vector b equals to x cap plus 3y cap.
00:58
Okay.
01:01
So now firstly it is as that draw the vectors on a carton.
01:05
Cartesian coordinate system x y z here.
01:12
Alright, so now we can draw here like this.
01:15
Let us say this is y, y -axis, x -axis, i'm sorry, x -axis, and here it will be like this...
