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:
NameError: name 'rewrite' is not defined
How i
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 sage-support,
Is there way to change the *order* that objects from a Graphics object
are plotted (i.e. the Z-order)? Consider the following code in the
notebook for a 2D plot::
p1 = plot(sin, 0, 10, thickness=10, color='green')
p2 = polygon([(0,0), (10,0), (10,1), (0,1)], color='gray')
p3

Hi all,
Here is a list:
mesures=[[172,91,57],[181,88,58],[146,88,56],[191,85,59],[171,92,50],
[157,93,55],[180,84,48],[142,77,60],[169,80,45],[162,76,59],
[167,104,73],[166,81,53],[145,78,59],[163,98,58],[192,90,50],
[184,85,60],[151,77,56]]
# [[P
return (t.real_part()+I*t.imag_part()).simplify_trig()
Thank you very much, i works.

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

Hi, I checked the FAQ in the sage documentation page, but didn't find

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
