Anyone good in Math? Retro? Explain to me 3D coordinates (X,Y,Z)?

I'm sorry but I'm honestly not sure what there is to explain or how best to do it.

Three dimensions - X is horizontal, y is vertical, and Z is best explained as depth. The origin in this case is like the center of a three dimensional box (with potentially infinite dimensions). Equations will include these three variables unless one of them is unused (a 2D line or graph can still exist on the 3D plane with some variable just being zero).

It's really easy once you jump the hurdle and get what's going on, and the equations are pretty easy to get used to.

For future reference you can always PM/Wall me about any math up to and including integral calculus, but not multivariate calculus and beyond, or linear algebra (yet, I think I have to take it).

Oh, x and y are horizontal (forward, backward, sideways). z is usually the vertical axis (up, down).



Your x and y coordinates change if you are walking on a flat surface. In an elevator, only the z coordinate changes.

Well, I should note this is also correct - the orientation of the model depends on the field you're discussing and/or the text you're referencing, but this I believe is more common in physics. And I don't do physics.

I did a LOT of 3D geometry a month back.

Speaking of x,y,z I quickly understood by taking a graph paper...and then drawing X&Y axes normally on it, as is done in 2D. My teacher said after this was done, put the tip of your pen at the origin, and make it perpendicular to the plane of your paper, and that, is Z axis.

Then, you mentally transpose this orientation on any 3 walls in a room and then you can fundamentally imagine coordinates in 3D space.

I hated 3D geometry though. It gets v annoying, especially stuff like Mirror image, foot of perpendiculars, Point of intersections between planes and points, between two planes.

Ewww, I've never seen Z coordinates but Lucifer can keep it

i was so good at math until we got to geometry, and then it just kept going downhill from there

Thanks Your explanation is really good as well. And the fact you can do integral calculus

Does he know that Bonsoir is Good evening? Please don't tell me he's using bonsoir in the morning, afternoon, evening and night? He needs to speak French properly, I would die if someone used these French greetings wrong. He's a TV character, research would have needed to be done on the language, you cannot just use French wrong, you need to know how to use the phrases in the first place, he just cannot use bonsoir any time of the day, Bonsoir is only to be used for the evening.

For me it was algebra. Letters shouldn't be in math.
