00:00In this question, we have a vector, and this projection is b vector.
00:04How much is b vector?
00:04Same by 3.
00:06We have lambda value asked.
00:08We will put formula in the formula.
00:10Some people have confusion.
00:12This is b vector or a vector.
00:16Some people have to forget it.
00:18So, we will put a vector in a vector.
00:22We will find a vector in a vector.
00:24So, the value of a vector will increase projection.
00:28We will put a vector in a vector.
00:29If we add a vector, it will increase the value.
00:34So, we will divide the formula in the formula.
00:35We will divide the magnitude of a vector.
00:41Then, the direction vector will increase the value.
00:43But we will increase the value in the section.
00:47Then, the value of a vector is not.
00:47In the denominator, there will not be a vector.
00:51It will not be a vector.
00:53This is the formula.
00:57So, A vector dot B vector I cp wali terms multiply
01:02ok jcp wali jcp cp kkp wali kcp cp
01:052 lambda minus 1 plus 2 lambda
01:09Under root B vector magnitude 4 plus 1 plus lambda is equal to 7 by 3
01:184 lambda minus 1 under root 5 plus lambda is equal to 7 by 3
01:23option put 1 by 1, so we put 2, because we see that 5 plus 4 is 9, so now
01:31we put 2, so
01:345 plus 4 is 9, so this is 3, so here we put 2, so here we put 2, so
01:45here we put 2, so
