Regarding linear independence

If a question asks to prove that vectors a, b and c are linearly independent,
can I prove that they are NOT dependent, hence independent?
ie. if a = mb + nc, there are no m, n values that satisfy the vectors, hence independent (or is this the only way, idk)
thanks

another question
is this correct?
Scalar resolute of in the direction of (or parallel to) is
Scalar resolute of perpendicular to is
quite weird.

Right and right.

For the first, you could also show m and n are either 0.

That *scalar* resolute always trips me up, i keep in onthing its a.b/b.b

thanks, i'd rather stick with one method approach :)
well you're not gonna have to remember the scalar resolute since we only have exam 2 left :D
