Third dimension

Why do you think it doesn't? There's all kinds of mathematics dealing with three independent variables, e.g. vector analysis.

Third dimension
Does third dimension necessarily means three varialbes?
I want to see a repertoir x,y,z not x , y axes like the gallelian repertoir.

Well if it didn't mean dealing with threee independent vaiables how are you going to handle 3 dimensions with only two variables ?
That I would like to see.

Perhaps a little thought before posting might not have gone amiss.

Re: Third dimension

What do you mean by "gallelian" and "repertoir?"

I know that there are three dimensions in my little cubicle here... but I can't tell you which of these dimensions is the "third" one.

I can do any number of matematical calculations based on one dimension (i.e. measure the distance between two points on my desk) or I can pick two dimensions (any two) and measure the area.

I can measure the area of my desk surface (which involves two measurements over two dimensions) or I can measure the area of my wall (i.e. two different measurements over two different dimensions).

I can also, by making three mesurements over three different dimensions figure out the entirely insufficient volume of this tiny space I am sitting in. This would be a calculation in three dimensions.

Of course calculations in one dimension require a lot less work than calculations in three dimensions. I would much prefer to do one-dimensional calculations which may explain why the problems you are given to solve tend to favor one and two dimensions.
