Hi everybody,
To become familiar with ODEs with Sage, I am trying to solve a very
simple ODE with the Laplace method implemented in Sage
In concrete, i want to solve
dy(t)/dt = -k*y(t)
with for example, initial conditions y(0)=1
For that:
t = var('t')
k = var('k')
y = function('y',t)
Hi all,
I'm glad to inform you about new quarterly release 0.34 of the OOSuite
package software (OpenOpt, FuncDesigner, SpaceFuncs,
DerApproximator) .
Main changes:
* Python 3 compatibility
* Lots of improvements and speedup for interval calculations
* Now interalg can obtain all solutions of

I do want to convert to an integer in this particular case...but
integers are rationals, so I don't understand why I don't just get the
integer 344 when I try the following code:
sage: K=Qp(7,5)
sage: Q=QQ
sage: a=344
sage: b=K(a)
sage: a=Q(b)

Here is the code that can be pasted into sage to produce the error:
sage: K=Qp(7,5)
sage: Q=QQ
sage: a=344
sage: b=K(a)
sage: a=Q(b)

I was hoping that new release 4.7 will fix the problem, seeing that
the ticket 5634 has been closed. However, I just tried to install a
new package and got an error message:

The following piece of code also seems to leak memory.
The problem seems to occur while resolving the action of ZZ on E.
sage: K = GF(155,'t')
sage: a = K.random_element()
sage: while 1:
: E = EllipticCurve(j=a); P = E.random_point(); 2*P;

Does this happen every time you start Sage? That is odd.
About that, see trac tickets 10303, 11077, 9960:

As I said previously, you are only going to reconstruct RATIONALs with
num,den less than sqrt((1/2)*p^k), i.e. 92 in this case. It is true
that the integers are a subset of the rationals, but the convert to
integer problem is not a sub-problem of the convert to rational
problem.
