Do I need to worry about warnings for malformed packages?

 Resolving package versions...
┌ Warning: malformed Pkg server value
│   server = "https://C:\\Users\\Brett\\AppData\\Local\\Programs\\Julia 1.5.3\\bin\\julia.exe"
└ @ Pkg.PlatformEngines C:\buildbot\worker\package_win64\build\usr\share\julia\stdlib\v1.5\Pkg\src\PlatformEngines.jl:605

HaZZa! It works, I have version version 4.0.6, and:

f(x)=x^2/x
f(5)
5.0
let ex = Differential(x)(f(x))
           func_ex = build_function(expand_derivatives(ex), x)
           @eval  ∂tk(x)= ($func_ex)(x)
       end
∂tk(x)

GalacticOptim.jl loads and works as well! I’ll play with it and go over calculus.

Can Nonlinear solve or NL solve be used for inequalities?
ie.

f(x)=(x^2)-4
solve(f(x)>0)
