Calculus and Vectors - Determining Vector and Parametric Equations

Click For Summary

Homework Help Overview

The discussion revolves around determining vector and parametric equations for a plane that contains a specific point and is parallel to another given plane. The problem involves understanding the relationships between points and vectors in three-dimensional space.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the formulation of the vector equation and question whether it correctly represents a plane. There are inquiries about the inclusion of the specified point in the plane and the necessity of maintaining parallelism with the given plane.

Discussion Status

Some participants have provided guidance on verifying the correctness of the vector equation and emphasized the importance of checking whether the plane contains the specified point. There is an ongoing exploration of how to construct the equation while ensuring it meets the problem's requirements.

Contextual Notes

Participants note the need to ensure that the derived plane equation correctly incorporates the point A(2, 3, -1) and maintains parallelism with the original plane, which may involve checking assumptions about the vectors involved.

Comment: Your vector equation isn't an equation. An equation always has '=' in it.
Can you check these for yourself? Does your plane contain the point A(2, 3, -1)? Since your plane is parallel to the given plane, it should contain the same two vectors as the given plane.

To obtain a plane parallel to P0 and passing through the point A(2,3,−1), all we need to do is add A as a vector (I dropped the coordinates for brevity) to all the points of P0. This gives us the plane

(𝑥,𝑦,𝑧)=𝐴+𝑠(5,2,−1)+𝑡(3,−2,4)

Yes,, I understand how you got the equation, but I was responding to your request for someone to verify that your work was correct. Here's what I said before:

One of the things I've always liked about mathematics, especially at somewhat higher levels, is that it's not difficult to verify your work for yourself. What I said above was how you can do this.
