(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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

2. Relevant equations

f(x) = sin(Mx)

g(x) = Bx + V

3. 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!
