Question in the Attachment. Hello, maybe someone can help me in answering.
was: Frage im Anhang Hallo, vielleicht kann mir Jemand bei der Beantwortung helfen.
Hi,
stetig (instead of the typo steitig) means continuous and diffbar is short for "differenzierbar", i.e. differentiable.
Cheers,
M.
PS: the question is not really Mathematica/Wolfram Language/Wolfram Alpha related.
We STRONGLY request that all posts be in English.
It is unlikely you could find a symbolic solution with Mathematica. A numerical solution from iterating is probably feasible.
"rk ist dieUnbekannte" ~ rk is the unknown
Google Translate did not know steitig and diffbar.
