I know that Riemann integral of this function doesn't exist and Lebesgue integral is 0, but I need formal writing of this problem.Yes, I can solve it.
Can you solve it? If not, then where are you stuck? What have you tried?
If you read the forum's posting guidelines and followed them, you would have received help by now.
If you want help, that is great, then read the posting guidelines and make an appropriate post.
Is the function continuous at every point in the domain?I know that Riemann integral of this function doesn't exist and Lebesgue integral is 0, but I need formal writing of this problem.
What can you tell about Lebesgue measures of the two subsets, i.e. the ones where [imath]f[/imath] is 0 and 1 respectively?I know that Riemann integral of this function doesn't exist and Lebesgue integral is 0, but I need formal writing of this problem.
