Linear dipendency means, that vectors can be expressed one through another
The magnitude or length of a vector is caculated by formula:
∣v∣=v12+v22+v32
How to find the vector between 2 point?
Substract coordinates of the first point from the coordinates of the second point.
A set of vectors in linearly independant if a sum of those vectors is equal to 0 zero only if all vectors are multiplied by 0.
A set of vectors is lenearly dependant if there exist numbers (except 0), at which vectors can be multiplied, such that the sum of those multiplied vectors will be zero.
Two vectors are orthogonal when their product returns a vector of 0.
