You can use something like this
dêkuji
merci
thank you for all the answers
always annoying to guess wether you should call maxima or not.

And I guess the answer to Paul's question is then:
sage: (sinh(log(t)))._maxima_().exponentialize().sage()
1/2*t - 1/2/t
sage: (cos(log(t)))._maxima_().exponentialize().sage()
1/2*e^(-I*log(t)) + 1/2*e^(I*log(t))

Hello,
there are a few weird results. I'd like to solve this homogenous edo :
$tx'=x+\sqrt{x^2+y^2}$.
using x=tu
sage: t=var('t')
sage: x(t) = function('x',t)
sage: id(t)=t
sage: u=function('u',t)
sage: d=diff(u*id,t)
