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 T_n(x) = \frac{\Gamma(1/2)\sqrt{1-x^2}}{(-2)^n\,\Gamma(n+1/2)} \ \frac{d^n}{dx^n}\left([1-x^2]^{n-1/2}\right)}
... is translated to the CAS output ...
Semantic latex: T_n(x) = \frac{\EulerGamma@{1 / 2} \sqrt{1-x^2}}{(- 2)^n \EulerGamma@{n + 1 / 2}} \deriv [n]{ }{x}([1 - x^2]^{n-1/2})
