Assignment 6: Problem 8 Previous Problem Problem List Next Problem (1 point) Are the functions f, g, and h given below linearly independent? f(x) = etz + cos(7x), g(x) = et - cos(7x), h(x) = cos(7x). If they are independent, enter all zeroes. If they are not linearly independent, find a nontrivial solution to the equation below. Be sure you can justify your answer. (etz + cos(7x)) + (etz - cos(7x)) + (cos(7:)) = 0
