Is there any way in Sagemath to find symbolically the local extrema of a given function?
Thanks for your answers!
**EDIT:**
As an example one may be interested in the extrema of the following differentiable function:
K=var('K');
l=var('l');
x=var('x');
z(x)=(cosh(-1/2*K*l+K*x)-cosh(1/2*K*l))/K; #Given functiondg.aragonesTue, 02 Jan 2018 12:13:50 +0100https://ask.sagemath.org/question/40437/min(f,g) where f and g take two variableshttps://ask.sagemath.org/question/8907/minfg-where-f-and-g-take-two-variables/Hi
Is it possible to create a function h(x,y) that would be the minimum (or maximum) of any two other 2-variable functions?
Like h(x,y)=max(f(x,y),g(x,y))? (this does not work)
This seems to be a rather useful function but I can't seem to find it.
any ideas?
Thanks
