Following up my previous message, here is an example:
%% begin shuffled list of exercises
\setuprandomize[2021]
\startluacode
function shuffle(tableau)
local maxsize, t, tt
maxsize = #tableau
tt = {}
t = {}
for i = 1, maxsize do
t[i] = {}
t[i]["columnOne"] = tableau[i]
t[i]["columnTwo"] = math.random(1,100*maxsize)
end
table.sort(t, function(a,b) return a.columnTwo < b.columnTwo
end)
for i = 1, maxsize do
tt[i] = t[i]["columnOne"]
end
return tt
end
\stopluacode
% We define three arrays
% with the names, the functions and their derivatives
% One could also add a ListOfVariables...
\startluacode
ListOfNames = {
"f",
"g",
"h",
"u",
"v",
"F",
"G",
"H",
}
ListOfFunctions = {
"\\cos(x^2)",
"x\\sin(x)",
"\\tan(x)",
"x^3 - 3x^2 + 1",
"\\frac{1}{1 + x^2}",
"\\sin(\\log(x))",
}
ListOfDerivatives = {
"-2x\\sin(x^2)",
"x\\cos(x) + \\sin(x)",
"1 + \\tan(x)^2",
"3x^2 - 6x",
"\\frac{-2x}{(1 + x^2)^2}",
"\\frac{\\cos(\\log(x))}{x}",
}
\stopluacode
\starttext
% We define a buffer and a shuffled list of integers
\startbuffer[test-derivatives]
\startluacode
ShuffledList = shuffle({1,2,3,4,5,6})
\stopluacode
Let $\cldcontext{ListOfNames[ShuffledList[\recurselevel]]}(x) :=
\cldcontext{ListOfFunctions[ShuffledList[\recurselevel]]}$. Prove that
\startformula
\cldcontext{ListOfNames[ShuffledList[\recurselevel]]}'(x) =
\cldcontext{ListOfDerivatives[ShuffledList[\recurselevel]]}
\stopformula
\stopbuffer
\dorecurse{6}{\blank[medium]{\bf Exercise #1.}
\getbuffer[test-derivatives]
}
\stoptext
%% end shuffled list of exercises
