Solve for x (complex solution)
x=-3i\ln(i\sqrt{4y^{2}-1}+2iy)+6\pi n_{1}\text{, }n_{1}\in \mathrm{Z}
x=-3i\ln(-i\sqrt{4y^{2}-1}+2iy)+6\pi n_{2}\text{, }n_{2}\in \mathrm{Z}
Solve for x
x=3\left(\arcsin(2y)+2\pi n_{1}\right)\text{, }n_{1}\in \mathrm{Z}
x=3\left(-\arcsin(2y)+2\pi n_{2}+\pi \right)\text{, }n_{2}\in \mathrm{Z}\text{, }|y|\leq \frac{1}{2}
Solve for y
y=\frac{\sin(\frac{x}{3})}{2}
