Are the functions f,g, and h given below linearly independent?

f(x)=0 g(x)=cos3x h(x)=sin3x

If they are not linearly independent, find a nontrivial solution to the equation below. Be sure you can justify your answer.

Not linearly independent.
Set C1=2 C2=0 C3=0
Then C1(0)+C2(cos 3x)+C3(sin 3x)=0 and since c1 nonzero, then the solution is nontrivial.

obviously NO , the zero function is never in a lin. ind. set

and what equation ?...do you read your query before asking ?
