If the multiplication sign * is absent ( say by mistake!) what is SAGE
evaluating?
For example:
x=var('x');f=1/((x-1)(x-3));
f.limit(x=1) returns -1/3
diff(f,x) returns -1/(x - 4)^2
plot(f,(x,0,10)) plots a smooth curve going through -1/3.
It is clear it is evaluating f =1/(x-4). How? Why is not p

Hi guys, back again.
It seems that I can never find what I look for in the reference documents,
but it always becomes embarrassingly easy once someone explains it to me.
I've been playing around with the displacement reaction for viscous drag
ballistics, and have derived the following equation:

I found this error.

Thank you very much, i works.

How i can exp(I*x) --> cos(x)+I*sin(x) ?
I wrote the following for personnal use :
def ThisIsEulerFormula(t):
"""
Return t, but in a simplified form.
We force Sage to see that exp(ix) is equal to cos(x)+i*sin(x) and
then to simplify the trigonometric expressions.

Hello, list, i need a function that can exp(I*x) --> cos(x)+I*sin(x)
At http://wiki.sagemath.org/symbolics/rewrite i found the rewrite
function. But this function is not mentioned in Sage reference manual,
and Sage 4.6.2 does not know this function:
