Hi, let's start the solution.
00:02
In this question we have given, a is 3 plus 2j and b is 2 plus bj.
00:12
And question says that find a plus b and b minus a.
00:15
First, we represent this a and b in a agen plane.
00:19
So we know that if z is equal to x plus zy, where x represent real part and y represents imaginary part.
00:33
For a, for first basically, we have this one.
00:41
Here we have one, two, three.
00:43
This is a real axis.
00:46
That is real of a and this one is real of not real.
00:51
That is imaginary of.
00:55
Imaginary of b.
00:58
So here by comparing we get x is three and y is two.
01:05
So we get one, two, three.
01:07
That this and one so this point we get this is the 3 plus 2 j represents the 3 plus 2 j argon now represent b in a organ plane that means for second so we get this one this one is real of b and this one of imaginary of b so here real is two and imagine is 2.
01:43
So here we get 1 to this one and 3 1 to 3.
01:47
So that means this point.
01:51
This represents 2 plus 3 .j.
01:58
So now we find a plus b and a minus b.
02:02
A plus b is 3 plus 2j plus 2j.
02:11
So by adding this we get 3 plus 2 is 5 and 2 z plus 3 j is 5.
02:15
So by adding this we get 3 plus 2 is 5 and 2 z plus 3 j is 5.
02:17
So we get a plus b is 5 plus 5 z.
02:24
Now represent a plus 5 sorry a plus b in a agen plane.
02:30
So then we get this one.
02:32
This is a real axis.
02:35
That is real and this one is imaginary axis.
02:39
Here we have 1, 2, 3, 4, 5 and this one is 1, 2, 3, 4, 5...
