Resol Y=e^aθ

$$Y = e ^ { a \theta }$$

Resoleu a (complex solution)

$$\left\{\begin{matrix}a=\frac{\ln(Y)}{\theta }+\frac{2\pi n_{1}i}{\theta }\text{, }n_{1}\in \mathrm{Z}\text{, }&\theta \neq 0\text{ and }Y\neq 0\\a\in \mathrm{C}\text{, }&Y=1\text{ and }\theta =0\end{matrix}\right,$$

Resoleu Y

$$Y=e^{a\theta }$$

Resoleu a

$$\left\{\begin{matrix}a=\frac{\ln(Y)}{\theta }\text{, }&\theta \neq 0\text{ and }Y>0\\a\in \mathrm{R}\text{, }&Y=1\text{ and }\theta =0\end{matrix}\right,$$
