limnesin(nπ+(1)n2e2n)=limnesin(π+(1)n2en2)=esin(π2)=elim supesin(nπ+(1)n2e2n)=ee2.718(approx.)andπ3.14(approx.)e<π lim supesin(nπ+(1)n2e2n)<π\lim_{n \to \infty} e^{\sin\left(\frac{n\pi + (-1)^n 2e}{2n}\right)} \\= \lim_{n \to \infty} e^{\sin\left(\frac{\pi + \frac{(-1)^n 2e}{n}}{2}\right)}= e^{\sin\left(\frac{\pi}{2}\right)} = e\\\therefore \limsup e^{\sin\left(\frac{n\pi + (-1)^n 2e}{2n}\right)} = e \\e \approx 2.718 \quad (\text{approx.})\quad \text{and} \quad \pi \approx 3.14 \quad (\text{approx.})\\\therefore e < \pi \implies \limsup e^{\sin\left(\frac{n\pi + (-1)^n 2e}{2n}\right)} < \pi
