Hi,
In `sympy 1.7.1`, this computation was giving the expected result:
``` python
import sympy as sp
x,y = sp.symbols('x y')
f = sp.Function('f')
g = sp.Function('g')
sp.dsolve(sp.diff(f(x),x)…

I don't know whether it's the problem of jupyter or sympy.
```python
diff(f(x)* g(…

We already do:
```
sage: sqrt(4/9*x)
2/3*sqrt(x)
sage: sqrt(-4*x)
2*sqrt(-x)
sage: (4*x + 12)^(-3)
1/64/(x + 3)^3
sage: (4/9*x)^(3/2)
8/27*x^(3/2)
```
This should be extended to rational exponents …

Here is the proposal we used in 2020. It was accepted, but was later cancelled when the conference changed to online-only. I also have the review comments but I don't know if those can be shared publi…

Hi, here the problem:
```
>>> x=symbols('x')
>>> p=zeta(x)
>>> p=p.diff(x, 3)
>>> p=p.subs(x, 4)
>>> N(p)
Traceback (most recent call last):

So, i played with the application icon a bit.
I like the GNOME style of icons, which try to have icons be a strong metaphor for the actual utility of the program. As Horizon fits in the GNOME ecosyst…

Hi,
I was getting random with an element created with the symbolic generation, so the header file is similar to others of the fluid dynamic app.
Finally I was able to track the problem to the BDF …

The functions in `transcentental.py` could return special values:
* `zetaderiv(0,1)=-1/2*log(2*pi)`, http://dlmf.nist.gov/25.6#E11
* `zetaderiv(0,2)=-1/2*log(2*pi)^2+...`, http://dlmf.nist.gov/25.6#…
