WebWe will show that Thomae’s function is Riemann integrable. We can take = 1 6. Every sub-interval of every partition between 0 and 1 contains an irra-tional number, because of this the lower sum of T with respect to each partition is 0. To show that T is integrable, we must nd a partition P , given >0, that the upper sum U(T;P ) < . WebBut we claim that the Thomae function is integrable on this interval: Example.
