Plotting and visualizing a 3D plot of a vector function

Click For Summary

Discussion Overview

The discussion revolves around the challenges of plotting a specific vector-valued function, r(u,v) = , in a 3D space. Participants explore methods for visualizing this function, including generating values for u and v and understanding the geometric nature of the resulting surface.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant expresses difficulty in plotting the vector function and mentions confusion when creating a table of values for u and v.
  • Another participant suggests starting with equal values for u and v and creating a loop to generate different points, implying this could simplify the plotting process.
  • A later reply notes that the values of Z become very high with small increases in u and v, indicating a challenge in visualizing the surface in 3D.
  • Some participants assert that the surface is a plane and suggest that any plane can be determined by plotting three points, although this approach does not clarify how to visualize the entire surface.

Areas of Agreement / Disagreement

Participants generally agree that the surface is a plane, but there is no consensus on the best method to visualize it or the challenges involved in plotting the function.

Contextual Notes

Participants mention the rapid increase in Z values with changes in u and v, which may complicate the visualization process. There is also a lack of clarity on how to effectively plot the function in 3D space.

Hello, I'm trying to figure out how to plot a certain vector valued function but I'm having a hard time.

The problem gives me the following vector valued function:

r(u,v) = <u + v, 3 - v, 1 + 4u + 5v>

I don't know how to plot this. So far I've tried making a table with some u and v values to get the x, y and z values so I can plot it, but it got too confusing.

Thanks in advance

Where did you try it? I think you can do it by starting to giving the same value to u and v. You can try to create a loop for u and v then for each value there will be different (r,u).

Trying on paper.

Got this table. The values of Z get too high after increasing u and v by a bit. I know the surface will be a plane, but I can't visualize it in a 3D space.
 
You know it will be a plane. Any plane is determined by three points. So just take three points, plot them and the plane through it is the one you're looking for.

So, like this:
