Hello, when executing the commands
t=var('t')
g(t)=t^2
diff(g,t)I get as a result:
t -> 2tI only want 2t and not the leading t ->
What can I do?
Thank you for your efforts,
Hans
The point is that g(t)=t^2 creates g as a "symbolic function" (properly a callable symbolic expression), whereas t^2 is a symbolic expression.
sage: g
t |--> t^2
sage: g(t)
t^2
sage: g.is_callable()
True
sage: g(t).is_callable()
FalseDifferentiating a functin gets you a function, whereas differentiating a symbolic expression gets you a symbolic expression :
sage: g.diff(t)
t |--> 2*t
sage: g(t).diff(t)
2*tHTH,
Thank you very much! It works !!
