Computer calculations made easy
It would be useful to have the conversion using OpenMath also for polynomials, in particular, I would like to have at least the conversion from OpenMath to Yacas of the...

Limit
I tried this limit ``` In> Limit(k, Infinity) (s11+s12*k)/Sqrt((w^2+s11)*(w^2+s11+k^2*s22+2*k*s12)) Out> (s11+s12*Infinity)/Sqrt((w^2+s11)*(w^2+s11+Infinity*s22+2*Infinity*s12)) ``` I was expecting ``` s12/Sqrt(s22*(s11 + w^2)) ``` See .
As mentioned in #272: Improve documentation on multivariate polynomials.
Hello, I am trying to implement [Low-order polylogarithms](https://en.wikipedia.org/wiki/List_of_mathematical_series#Low-order_polylogarithms). I have tried these rules: ``` SumFunc(_k, 1, _n, _k * (z_IsFreeOf(k)^k), z*( 1 - (n+1)*z^n + n*z^(n+1))/((1 - z)^2)); SumFunc(_k, 1,...
Yacas can't integrate `1 / (1 + Sqrt(x))`: ``` In> Integrate(x) 1 / (1 + Sqrt(x)) Out> Integrate(x)1/(Sqrt(x)+1) ``` The integration is not difficult via a substitution `u = 1...
