ແກ້ D=4frac{e^-s^frac{3{2}}}{sin(pi/4)}

$$D = 4 \frac { e ^ { - s ^ { \frac { 3 } { 2 } } } } { \sin ( \frac { \pi } { 4 } ) }$$

ແກ້ສຳລັບ D (complex solution)

$$D=\frac{8i}{e^{s^{\frac{3}{2}}+\frac{\pi i}{4}}-e^{s^{\frac{3}{2}}-\frac{\pi i}{4}}}$$

ແກ້ສຳລັບ s (complex solution)

$$\left\{\begin{matrix}s=\frac{\left(-2\ln(D)-4\pi n_{1}i+5\ln(2)\right)^{2}}{4}\text{, }n_{1}\in \mathrm{Z}\text{, }arg(-\ln(D)-2\pi n_{1}i+\frac{5\ln(2)}{2})<\pi \text{, }&D\neq 0\\s=0\text{, }&D=2^{\frac{5}{2}}\end{matrix}\right,$$

ແກ້ສຳລັບ D

$$D=\frac{4\sqrt{2}}{e^{s^{\frac{3}{2}}}}$$

$$s\geq 0$$

ແກ້ສຳລັບ s

$$s=\frac{\sqrt[3]{2}\left(-2\ln(D)+5\ln(2)\right)^{\frac{2}{3}}}{2}$$

$$D>0\text{ and }-\ln(D)+\frac{5\ln(2)}{2}\geq 0$$
