Question: are sinx and sin2x linearly independent?
Answer: Then f(π/2) = 2(1)(−1) − 0 = −2, so sin x and sin2x are linearly independent. ... So the Wronskian does not tell us whether the functions are linearly dependent or independent. Since the Wronskian is 0, let us first try to show that the functions are linearly dependent. We can get −2x2 from f by multiplying by −2.
