Thanks. That seems more errors. `integrate(x^(1/2)*(1+x)^(-23/10),(x,0,1))` PyError ($(Expr(:escape, :(ccall(#= /Users/gangchen/.julia/packages/PyCall/ttONZ/src/pyfncall.jl:44 =# @pysym(:PyObject_Call), PyPtr, (PyPtr, PyPtr, PyPtr), o, pyargsptr, kw))))) _CoeffExpValueError('expr not of form a*x**b: 0.857109621959463') File "/Users/gangchen/.julia/conda/3/lib/python3.7/site-packages/sympy/integrals/integrals.py", line 1477, in...

Although the int power function works. ` integrate(x^(2)*(1+x)^(-3),(x,0,1))` `−5/8+log(2) `

Do you want to add "Asymptotic solutions of differential equation, Asymptotic Expansion of Integral" in Symbolics? And something like Pattern selection and replacement (Cases[], Replace[] in Mathematica) also very useful...

Let me state the question exactly: ``` @variables t α σ(..) β[1:2] @variables w(..) x(t) y z(t, α, x) expr = β[1]* x + y^α + σ(3) * (z -...

very nice! I also tested other functions in Symbolics.jl, looks very cool! Although temporary it seems very slow comparing with SymEngine.jl , like "expand" and "substitute" function, I believe the...

I also can not install it using Pkg.add("Mathematica"). The interface will be quite useful if it can works for Julia 1.x. But it seems the contributors do not make any...
