Homework Help Overview

The discussion revolves around the representation of a geometric figure defined by parametric equations, specifically the conversion of these equations into the standard form of a plane equation. The subject area is primarily related to geometry and vector mathematics.

Discussion Character

  • Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants explore the nature of the given equations, questioning whether they represent a plane or a line. There is a discussion about the implications of the parameterization and the dimensionality of the figure.

Discussion Status

Participants have identified that the original equations describe a line rather than a plane, with some expressing confusion over the terminology used. A clarification regarding the nature of the figure has been provided, leading to a better understanding of the problem context.

Contextual Notes

There is mention of a potential error in the original problem statement, indicating that the term "plane" was incorrectly used instead of "line." This has contributed to the confusion in the discussion.

Hi all, I have a plane defined like this:

x = 2 +t
y = 2+t
z = t

How do I put it in the format:
Ax + By + Cz = D?

I feel stupid! :confused:
 
Physics news on Phys.org
So it is the line through (2,2,0) and parallel to the vector v = (1,1,1)

Why is it not parallel to the vector v = (1,1,1)?
 
You may want to investigate this: http://mathworld.wolfram.com/Plane.html" .

Well, feel only a little bit stupid!:rolleyes: That's not the equation of a plane! Since x, y, z depend on a single parameter, t, it is the equation of a one-dimensional figure. Since the functions are linear, it is the equation of a line, not a plane.
 
Ah ok, thanks for all the help!
 
Guess what? Turns out it was a textbook orthographical error. It was supposed to be "line" not "plane." And I was stumped for so long!
