Hi everyone,
I just checked out one of first page in the "Constructions" page:
http://www.sagemath.org.nyud.net/doc/constructions/calculus.html
Just after the first example "Differentiation"
sage: var('x k w')
(x, k, w)
sage: f = x^3 * e^(k*x) * sin(w*x); f
x^3*e^(k*x)*sin(w*x)
sage: f.diff(x)
k*x^3*e^(k*x)*sin(w*x) + w*x^3*e^(k*x)*cos(w*x) + 3*x^2*e^(k*x)*sin
(w*x)
sage: latex(f.diff(x))
k x^{3} e^{\left(k x\right)} \sin\left(w x\right) + w x^{3} e^{\left(k
x\right)} \cos\left(w x\right) + 3 \, x^{2} e^{\left(k x\right)} \sin
\left(w x\right)
there is
"If you type view(f.diff('x')) another... "
When I do that, I get a long error message, which could frighten off
(it is the first example...). With "view(f.diff(x))" it works.
However, if the function is defined via
f = maxima(....)
then both ways work: view(f.diff('x')), view(f.diff(x))
I don't know if this is intended, but at least on the website it
should be changed, not to get the error.
Greets,
Stefan
