Answer

$\lim\limits_{x\to\frac{1}{2}^-}(x\sec{(\pi x)})=+\infty.$

Work Step by Step

$\lim\limits_{x\to\frac{1}{2}^-}(x\sec{(\pi x)})\to$ $\lim\limits_{x\to\frac{1}{2}^-}(x)=\dfrac{1}{2}^-=\dfrac{1}{2}.$ $\lim\limits_{x\to\frac{1}{2}^-}\sec{(\pi x)}=\sec{\frac{1}{2}^-(\pi)}=+\infty.$ By Theorem $1.15:$ $\lim\limits_{x\to\frac{1}{2}^-}(x\sec{(\pi x)})=+\infty.$
