Let and
be vectors in
. Find a point
such that
are the vertices of a right triangle.
We choose to be a point such that
is orthogonal to
(so we have a right angle). So,
The choices of and
are arbitrary, so let’s take
, then we have
. Therefore
is a solution.
the vector formed by (A-B)=(-1,3,5), right? Why in the resolution the results is “(-1,3,-5)”, correct me if I’m wrong please, I’m VEEEEEEERY confused.
