Equation of a line from Parametric equations

Click For Summary

Homework Help Overview

The discussion revolves around finding the equation of a line from given parametric equations, specifically x(t) = 1 + 2t, y(t) = -1 + 3t, and z(t) = 4 + t. Participants are exploring the relationship between parametric equations and their corresponding line equations.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to relate the parametric equations to a standard line equation format, expressing uncertainty about the next steps. Some participants suggest alternative forms of the line equation and question the correct approach to derive the equation of a plane containing the line.

Discussion Status

The discussion is ongoing, with participants sharing different interpretations of the equations and expressing confusion about the next steps. There is an exploration of how to derive the normal vector for the plane equation based on the line's direction.

Contextual Notes

Participants note the additional requirement of finding the equation of a plane that contains the line and a specific point, which adds complexity to the problem. There is uncertainty regarding the necessary components to derive the normal vector for the plane.

How does one find the equation of a line from parametric equations?

In spefiic I'm looking at this: x(t) = 1+2t , y(t) = -1 + 3t , z(t) = 4+t... I think i got to use something liek x-1/a = y-1/b=z-1/c or something like that. If what i just said is true, then I'm lost on what to do next.


Thanks
 
Physics news on Phys.org
t = (x-1)/2 = (y+1)/3 = z-4
 
or wait... do i uses this:

<x_0,y_0,z_0>+ t<a,b,c> ...


now I'm really confused.
 
Yeah tide, i did that, but then isn't there something else i got to do? I don't know I'm kinda confused about this stuff. Also allow me to add the rest of the question. IT's find the equation of a plane containing that line, and the point (1,-1,5). Sooo i need the N =<a,b,c> vector and a point ot get my equation of a plane.. So could i use use the second half of that equation i posted aboce ( t<a,b,c>) to get what i need for my N vector?
