Question

Would love help on this multivariable calc question.

Answer 1

Maybe? :]

Answer 2

Here it is, question 1

Answer 3

Ooooh dang sorry I don't think I can do this one >.< Sorry dude

Answer 4

No problem

Answer 5

I can't even understand what the question asks,

Unless it means that V is a Vector that is actually the normal vector n

Answer 6

not to know i'm not given anything....

Answer 7

Just how my professor is I suppose. He never provides constants. My assumption is that n is a separate orthogonal unit vector and v is a different 3D vector. Regardless, thanks for the interest at least.

Answer 8

couldn't you say that:
\[c = v * n\]
(where * is the dot product)

Answer 9

and that v perpendicular to the plane is c(n hat)

Answer 10

It's been a decade or so since I've done this stuff.. it looks like it just wants it all general according to definitions.
Here's some stuff: http://www.euclideanspace.com/maths/geometry/elements/plane/lineOnPlane/index.htm
