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 \mathrm{ber}_n(x) = \left(\frac{x}{2}\right)^n \sum_{k \geq 0} \frac{\cos\left[\left(\frac{3n}{4} + \frac{k}{2}\right)\pi\right]}{k! \Gamma(n + k + 1)} \left(\frac{x^2}{4}\right)^k ,}
... is translated to the CAS output ...
Semantic latex: \Kelvinber{n}@@{(x)} =(\frac{x}{2})^n \sum_{k \geq 0} \frac{\cos [(\frac{3n}{4} + \frac{k}{2}) \cpi]}{k! \EulerGamma@{n + k + 1}}(\frac{x^2}{4})^k
