Best ResponseYou've already chosen the best response.0Multiply each vector with C's and then set the linear combination of them equal to zero. Solve for each component. If you eventually find that the C's are nonzero, you can conclude that the vectors are dependent. If they equal zero, they are linearly independent. Depending on whether the vectors are solutions to a differential equation, you can also use the Wronskian.

Best ResponseYou've already chosen the best response.0the question is if the vectors B1,B2..Bn is linearly dependent, then any collection of vectors which contains these vectors is also linearly independent....which is easy

Best ResponseYou've already chosen the best response.0The idea is, the vectors are parallel, then they can be scalar multiples of eachother. That implies that \[C_1\] and \[C_2\] are constants, therefore they are dependent.

Best ResponseYou've already chosen the best response.0Same idea as the last part. If vectors are colinear in the plane, then they must be dependent. If not, a linear combination of any two vectors can be colinear with the other, meaning that they are linearly dependent. Same logic, more gimmicks.

Best ResponseYou've already chosen the best response.0So if they are all in the same plane, they can be represented by some variation of (S1V1+S2V2=a)

Best ResponseYou've already chosen the best response.0Pretty good. I'm not too worried, just gotta be able to derive something if I go absent minded.
