Manual adding table in Maple and then add plots into the cells is probably not useful for you?

Got this from someone else here on forum

## f := x -> x^sin(x):Inflpts := [fsolve...

```

f := x -> x^sin(x):

Inflpts := [fsolve(D(D(f))(x), x=0..16, maxsols=6)];

Q := map(p->[p,f(p)], Inflpts):

T := seq(plot(D(f)(p)*(x-p)+f(p), x=p-1..p+1, color=red), p=Inflpts):

plots:-display(plot(f, 0.0..16.0, color=black), T,

plots:-pointplot(Q, symbolsize=10, symbol=solidcircle, color=blue),

map(p->plots:-textplot(evalf[4]([p[1]-sign(D(f)(p[1]))*2/3,p[2]+1,p]),

font=[Times,8]),Q), size=[800,400]);```

a example fo infliction points, can be adjusted for find min/max  :to give a idea

FactorSteps(Y^2*x^3-x^3);
How about for complex numbers ?
