For each positive integer n≥1n \ge 1n≥1, we define the set of real numbers: Tn={x∈R:cos⁡(2nπx)=1}T_n = \left\{ x \in \mathbb{R} : \cos(2^n \pi x) = 1 \right\}Tn​={x∈R:cos(2nπx)=1} Determine the union U=⋃n=1∞TnU = \bigcup_{n=1}^{\infty} T_nU=⋃n=1∞​Tn​ and the intersection I=⋂n=1∞TnI = \bigcap_{n=1}^{\infty} T_nI=⋂n=1∞​Tn​.
