Division by zero sources:

$\begin{array}{r}{\left(\sqrt[\oplus ]{\epsilon }\right)}^2=\frac{1\ominus \delta \ominus \varphi }{1\ominus \delta \oplus \varphi }\\ {\left(\sqrt[\oplus ]{\epsilon }\right)}^2=1\ominus \frac{S(\varphi )}{S(1\ominus \delta )}\\ C_{1/2}\left(\epsilon \right)=\frac{S(\varphi )}{C(\delta )}\end{array}$

Or as angle measures:

$\cos \frac{1}{2}\epsilon =\frac{\sin \varphi }{\cos \delta }$

$x=a_0+\genfrac{}{}{0ex}{}{}{|}\frac{1}{a_1}\genfrac{}{}{0ex}{}{|}{}+\genfrac{}{}{0ex}{}{}{|}\frac{1}{a_2}\genfrac{}{}{0ex}{}{|}{}+\genfrac{}{}{0ex}{}{}{|}\frac{1}{a_3}\genfrac{}{}{0ex}{}{|}{}+\genfrac{}{}{0ex}{}{}{|}\frac{1}{a_4}\genfrac{}{}{0ex}{}{|}{},$

$x=a_0+\frac{1}{a_1+}\frac{1}{a_2+}\frac{1}{a_3+}\frac{1}{a_4}$

$x=a_0+\frac{1}{a_1}\genfrac{}{}{0ex}{}{}{+}\frac{1}{a_2}\genfrac{}{}{0ex}{}{}{+}\frac{1}{a_3}\genfrac{}{}{0ex}{}{}{+}\frac{1}{a_4}.$
