Spherical coordinates position vector

Click For Summary
SUMMARY

The discussion focuses on determining the position vectors of points P and Q on a diameter perpendicular to the plane formed by points U, V, and W on a unit sphere centered at the origin. Participants emphasize the need to establish coplanar vectors using the position vectors u, v, and w corresponding to points U, V, and W. The method to find a vector perpendicular to these coplanar vectors involves utilizing the triple scalar product, which is essential for calculating the normal vector to the plane defined by the three points.

PREREQUISITES
  • Understanding of spherical coordinates and unit spheres

can anyone help me with this question:
A sphere of unit radius is centered at the origin. points U,V & W on the surface of the sphere have vectors u,v & w. find the position vector of points P&Q on a diameter perp to the plane containing points U,V & W?

can anyone help
 
Physics news on Phys.org
In Cartesian coordinates if the points U, V, W are coplanar, to which position vectors u, v, w point, respectively, what can one do to create two planar vectors? Hint. What is the formula for the vector pointing from U to V? Similarly for V to W or U to W.

Now with two coplanar vectors, how does one find a vector perpendicular to those two?
