Solution

To find the vector equation of a plane in R4\mathbb{R}^4 that passes through the point p=(1,3,5,2)p = (1, 3, 5, -2) and has the direction vectors v=[0,2,2,3]v = [0, 2, -2, 3] and w=[1,1,1,1]w = [1, 1, -1, 1], you can use the following vector equation:

x=p+sv+twx = p + sv + tw

Where:

  • xx is any point on the plane,
  • pp is the given point on the plane (1,3,5,2)(1, 3, 5, -2),
  • vv and ww are direction vectors, and
  • ss and tt are scalar parameters.

Now, breaking this down step by step:

  1. The position vector of the point pp is: p=[1,3,5,2]p = [1, 3, 5, -2]

  2. Add the direction vector vv scaled by ss: [ s[0, 2, -2, 3] = [0, 2s, -2s, 3s] ]

  3. Add the direction vector ww scaled by tt: [ t[1, 1, -1, 1] = [t, t, -t, t] ]

Thus, the vector equation for the plane is:

[ x = [1, 3, 5, -2] + s[0, 2, -2, 3] + t[1, 1, -1, 1] ]

Expanding this:

[ x = [1, 3, 5, -2] + [0, 2s, -2s, 3s] + [t, t, -t, t] ]

Final answer:

x=[1+t,3+2s+t,52st,2+3s+t]x = [1 + t, 3 + 2s + t, 5 - 2s - t, -2 + 3s + t]

This is the vector equation of the plane in R4\mathbb{R}^4.
