(a) If $p>1$, prove that the integral $\int_{1}^{+\infty} x^{-p} \sin x\ d x$ exists both as an improper Riemann integral and as a Lebesgue integral. (b) If $0<p \leq 1$, prove that the integral in (a) exists as an improper Riemann integral but not as a Lebesgue integral. Hint. Let

$$g(x)=\left\{\begin{array}{l}{\frac{\sqrt{2}}{2 x}} \\ {0}\end{array}\right.$$

if $m+\frac{\pi}{4} \leq x \leq m+\frac{3 \pi}{4}$ for $n=1,2, \ldots$ otherwise, and show that $\int_{1}^{a \pi} x^{-p}|\sin x| d x \geq \int_{\pi}^{n \pi} g(x) d x \geq \frac{\sqrt{2}}{4} \sum_{k=2}^{n} \frac{1}{k}$.
