求解 {l}{12sin(θ)=13}{a={(5)}}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 12 \sin(\theta) = 13 }\\ { a = {(5)} }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

求解 θ, a, b 的值

$$\theta =2\pi n_{1}+\frac{-2i\ln(2)+\pi +2i\ln(3)}{2}\text{, }n_{1}\in \mathrm{Z}\text{, }a=5\text{, }b=5$$

$$\theta =2\pi n_{2}+\frac{-2i\ln(3)+\pi +2i\ln(2)}{2}\text{, }n_{2}\in \mathrm{Z}\text{, }a=5\text{, }b=5$$
