LaTeX to CAS translator
This mockup demonstrates the concept of TeX to Computer Algebra System (CAS) conversion.
The demo-application converts LaTeX functions which directly translate to CAS counterparts.
Functions without explicit CAS support are available for translation via a DRMF package (under development).
The following LaTeX input ...
{\displaystyle \operatorname{Ci}(x)= \gamma+\ln x+\sum_{n=1}^{\infty}\frac{(-1)^{n}x^{2n}}{2n(2n)!}=\gamma+\ln x-\frac{x^2}{2!\cdot2}+\frac{x^4}{4! \cdot4}\mp\cdots}
... is translated to the CAS output ...
Semantic latex: \operatorname{Ci}(x) = \EulerConstant + \ln x + \sum_{n=1}^{\infty} \frac{(-1)^{n}x^{2n}}{2n(2n)!} = \EulerConstant + \ln x - \frac{x^2}{2!\cdot2} + \frac{x^4}{4! \cdot4} \mp \cdots
