### Current situation
The front-end (interface) of the ODE solver only takes one dependent variable. When we solve the second-order ODE, we will rewrite it as two first-order ODEs.
For example:

Package now compiles out of the box! There will be a next ticket for its interface within Sage.

`nonlinsolve([h - 1, k - 1, f - 2, f - 4, -2*k], h, k, f)` returns `{(1, 1, f)}`, but this system doesn't have a solution.

The new atlas release now builds netlib lapack itself, so the lapack tarball is now included in the ATLAS spkg.
* Updated to newest upstream source, various patches are no longer required

Hi,
While solving a set of differential equations:
free_eq = [m1*(d(x1,t,2)) + k1*x1 + (k2/alpha)*sinh(alpha*(x1-x2)), m2*(d(x2,t,2)) - (k2/alpha)*sinh(alpha*(x1-x2))]
The function get_harmon…

Often, one wants to define a permutation group on a set other than ` {1,2,...,n} ` such as say ` {'a', 'b', 'c', 'd'} `.
For example,
```
sage: G = PermutationGroup([ [('c','d')], [('a','c')] ])

The `Integral(...).n()` works, but the same `integrate(...)` hangs:
```
In [1]: Integral((3*x**3-x**2+2*x-4)/sqrt(x**2-3*x+2), (x, 0, 1))

From yesterday, every 10 minutes I take measurements (NodeMCU + CCS811). In the code I have ```delay (300000);```. I send measurements to my InfluxDB database. I visualize them using Grafan. Here are …
