hmm I can't see the error myself yet, my only guess could be with the fixated values.

i know that the 3 is wrong but idk why

The Jacobian Matrix looks right to me too, have you tried with different fixated values? other critical points I mean, I see you have found three of them.

yea and they all seem to be wrong somehow one of the values in the jacobian end up being wrong

so it seems like the critical points are the problem then, not your setup.

\[\Large x'=y \\ \Large y'=3x3x^3 \] yes?

but my critical points are correct because in a previous question it asked to solve for all the critical points and this was a follow up question

when i plugged in the critical poiints into the jacobian there was an algebraic error so the jacobian wouldve been 0 1 6 0

point (1,0) huh?
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
hmm I understand it for that point, but I am not sure why point (0,0) shouldn't work, if it's in fact a critical point.

ranyai12 Group TitleBest ResponseYou've already chosen the best response.1
because this question is asking for the first critical point we found, which we had to put in order from lowest value ot highest, and so we had to use (1,0)

Oh I understand, I wasn't aware of that. (: Well, well done!
