(6) det (W(sin(t),cos(t),exp(t))) = −2 exp(t) which indicates that these functions are linearly independent We will now show that if the Wronskian of a set of functions is not zero, then the functions are linearly independent

16 fév 2007 · if v = 0 Therefore, any set consisting of a single nonzero vector is linearly independent is linearly dependent if and only if at least one of the vectors in the set can be expressed as a linear combination of the others c1v1 + c2v2 +···+ ckvk = 0
[PDF] Linear Independance - MIT OpenCourseWare
we again see the danger of one function being a linear combination of some others that time, we shall revisit linear independence from a more general point of view equivalent to the family represented by equation (11, even though two arbitrary under what conditions can we tell that the constants in (4) cannot be
