Homework Statement
Okay so the question is to show that these 2 functions are linearly dependent.
ie. they are not both solutions to the same 2nd order, linear, homogeneous differential equation for non zero choices of, say M, B and V
Homework Equations
f(x) = sin(Mx)
g(x) = Bx + V
The Attempt at a Solution
So they would be dependent if their Wronskian is equal to 0.
W = Bsin(Mx) - (Bx + V)Mcos(Mx)
I'm stuck at this point.. I can't seem to find any identities to make this = 0. I've tried expanding too.. I don't think it helps much. Any help is appreciated!
