hello sage users and developers.one of my friend asked me the
following questions.can you please give the sufficient information?
I want to ask that what is the use of sage? Why should we use it?
Where its being used till date?
These questions might be simple and i want to know before i go deep

That's kind of impossible to answer. Imagine if somebody asked you:
What is the use of mathematics? Why
Hi Priyanka,
I would first define well the problem and the equation (you have terms like
c, and d that you are not using). It seems like you are trying to solve the
equation of a undampened string with a constant attached to it.
I would do it like this:
x = var('x') # independent variable
b =
That's specifically the kind of questions that make me hate the scientific
spirit.
Prove it, or it does not exist, instead of It looks like it exists but I
don't get how.
I think that Sage is useless, and as the mathematics that made me work on
it are totally useless too I do not mind much.
William,
I think you are being overly negative, although I agree the question
could have been put a little better.
If someone is thinking of using Sage in industry, they are likely to
want to know how much it is used in industry.
I think I'd answer this by pointing out some of the advantages

Hello, John, thank you for your answer! I must have missed the mail about
thread update, sorry for late reply.
I will think about your solution.

Hola,
would anybody be so kind and explain to me the mechanism behind
assume(sth)?
I strive to understand (without success, unfortunaly) following behavior:
sage: assume(x-2 = 0)
sage: assumptions()
[x - 2 = 0]
sage: assume(x-1 = 0)
sage: assumptions()
[x - 2 = 0]
x-1 = 0 is not

The mechanism seems to be broken. Actually, the mechanism that compares
boolean expressions seems to be broken, which means that assumptions
Is there any way to fix it (at least by yourself, in Sage's source code) ?

I would do it like this:
x = var('x') # independent variable
b = var('b') # constant
y = function('y', x) # unknown function
# define 2nd order ODE; (undampened spring with unit of mass attached)
myode = diff(y,x,2)+b*y == 0 # define 2order ODE
assume(b0) # mass is always possitive
