Hi Jaakko,

In sage, let's define:

Thanks for the reply. But no. The problem is not due to the fact that
the function has a singularity. Indeed.
plot(20*log(abs((1+I*x)^4),10),(x,0,3))
fails with the same error which is incomprehensible to me.
On the other hand turning the expression into a lambda function made
it possible to plo

Uh, not the documentation -- I found the *code* and learned from it...

Meanwhile I think it would really make sense to use constructions. It

I found substitute_function() useful for other purposes, but it wasn't
useful in this case since I didn't want to replace all instances of

Hi!
I have a question on the coercion model. Assume that we have two
rings R1,R2, so that there is no coercion from R1 to R2 and no
coercion from R2 to R1. The classical example is R1=QQ and R2=ZZ['t'].
Now let p1,p2 be an element of R1,R2, respectively. I want to multiply

The answer of this
f(x) = abs((1+I*x)**4+4)
f(1)
is 0.
Then the logarithm produces -infinity.
Maybe your parenthesis of abs are
