Determine whether the pairs of functions are linearly independent or linearly dependent on the real line 2 2 ( ) , ( ) cos sin f x g x x π = = + x Recall that =1
(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
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

These constants can be determined if we specify not only the function u but also the If these functions are linearly dependent, then c1 cosx + c2 sinx = 0 for all real This is a system of two linear equations in the two unknowns c1 and c2 For
