Challenge Problems
Push your limits with challenges.
Question 1
Analyze the function f(x) = |sin(x)/x| for x != 0 and f(x) = 0 at x = 0. Is it Fourier integrable? Discuss the conditions.
💡 Hint: Evaluate the behavior around 0 and its integral over the relevant range.
Question 2
Demonstrate that the function f(x) defined as 1 for rational x and 0 for irrational x fails to meet the criteria for Fourier integrability.
💡 Hint: Consider the density of rational numbers in any interval.
