    [sin(t) , cos(t), e^t] are these linearly dependent?

    thank you daniel:)

    if we don't have nontrivial solution for the combination of n vectors then these n vectors are said to be linearly dependent. I know the DEFINITION just i cannot show that rule for sin cos & e ?!? am I not clear yet? :(

    [sin(t) , cos(t), e^t] are these linearly dependent?

    No it just asks whether they are dep or in dependent. for ex if it would have given me sets like v=(0,2,3) , u=(1,2,3,) & z=(1,1,0) then i could write Av+Bu+Cz=0 and I could show that they are indep of not just by assuming one of the coef. is not zero. but i cannot show this with cos sin & e

    [sin(t) , cos(t), e^t] are these linearly dependent?

    I'm trying to prove that they are whether dependent or independent. how can I show iy?

    [sin(t) , cos(t), e^t] are these linearly dependent? can someone solve this q? I write Asint+BcosT+C(e^t) = 0 but then i cannot proceed...
