Find a vector which is orthogonal to

What do you mean with

*"with respect to"*? Are you searching vector orthogonal to ? - September 16th 2009, 12:02 AMroshanhero
No

Then please answer the question. What does " orthogonal to

**with respect to**" mean? I know what it means for two vectors to be "orthogonal" but not "with respect to" a third vector. Could you possibly mean "orthogonal to**both**and "? Or are you asking about the "Orthogonal projection of on ? - September 16th 2009, 06:21 AMmr fantastic
is standard notation for coordinates of points. So what yu have posted is qute ambiguous. Are we meant to assume that P is a vector given by <1, 2, 3> and Q is a vector given by <0, -2, -3>?

Also, I support the several requests for clarification of the question.
