So, we are given that to describe the 3d surfaces, inverse and draw the graph of it.
00:13
So, for that, first of all, if you see that, for the a part of this question, it is a plane passing through origin, passing through origin, that you can clearly see by the means of the equation standing upright on standing upright on the z -axis and equally inclined and equally inclined to x and y axis so what was the graph basically so it is nothing but y is equals to x this is what the equation we have given and the required graph is this one which we have generated by using the 3d software so clearly you can see this 3d surface of the graph is passing throughout this origin and is standing upright onto the z axis while equally inclined to xy.
01:27
So this will be the required answer to only a part of our question.
01:34
Now in similar way we can do it for the b part also in which you can see the equation is given x minus 1 of whole square plus z minus 1 of whole square is equals to 4 with y is equals to z square.
01:52
So let's check out out what will be the dimension and how the graph it will be.
01:58
Basically if you see this is nothing but indicating the equation of cylinder because see this one representing the equation of circle while y is equals to z square is added so that is makes in cylinder.
02:11
So let's have a look at diagram first.
02:13
So see this is what the graph of the given equation...
