I think this is a trig function.

 

Let \(x\) be a real number such that the five numbers \(\cos(2 \pi x)\)\(\cos(4 \pi x)\)\(\cos(8 \pi x)\)\(\cos(16 \pi x)\), and \(\cos(32 \pi x)\) are all nonpositive. What is the smallest possible positive value of \(x\)?

since you are much nicer and now understands what you have done, I have given a +1 to you, and I will try to solve this problem as best as I can:)
