Hello everyone, in this question we have given x, y, z, these triplets.
00:06
So, now we need to tell the restriction on the following four cases.
00:11
So, first case is when a point is on y axis.
00:18
So, clearly when point is on y axis that means it is not in x and z axis.
00:24
So, clearly those variables are 0 and y can be any number.
00:28
So, we can say that y can be belongs to any real number.
00:32
Now, in part b we need to tell a point on z axis.
00:36
So, now clearly in this we don't have any point at x axis and y axis.
00:41
So, basically on z axis and clearly z belongs to r...
