Hi, we are just given here we have l equals and is equal to n equal to one.
00:04
The element are the depression cosine.
00:06
So i understand here about addressing cosine, we just take here a point b, a, b, a, c, b, a, c, and this three dimensions here we have.
00:15
So this is the distance from origin that is given as r, theta, 2, theta, to the angles made by op, vector with x, y, and x, x, so we have r is given as square 2 plus b squared plus t squared.
00:26
So l is expression cosine for x x, p with this vector x, that is given as 4 theta 1, that is coming to be this is a so a over root a square plus b square plus c squared similarly we can find out m and so now it is given that lm l equal to m equal to n equal to one so if we have let's say on the x x x x x x x x x this are merges with a for the x xxx so for the x x x so for x x x x x x x is will be detection cosine or uh the points will be given as the what's coming out to be, we have 1 -0 .0.
01:09
So we can write in the way, just a moment.
01:14
So for the axis we have, you can addrescent cosine, we'll represent here given as 1, 0.
01:20
Because we have this co -seta 1, that is coming out to be a over a, that's coming out to be 1.
01:26
Then b is 0 on the x -axis, and next we have c is 0.
01:30
So that's coming out to be 0 0...
