Hello, my son found drawbacks typing the solution of this problem, I checked
the code and where is

$ans=Formula("sin(x^$b)^$a/sqrt(x^4+1)+sin(x^$b)^$a*$a*cos(x^$b)*x^$b*$b/(sin(x^$b)*sqrt(x^4+1))-2*x^4*sin(x^$b)^$a/sqrt{(x^4+1)^3}");

it should go

$ans=Formula("sin(x^$b)^$a/sqrt(x^$c+1)+sin(x^$b)^$a*$a*cos(x^$b)*x^$b*$b/(sin(x^$b)*sqrt(x^$c+1))-$c/2*x^$c*sin(x^$b)^$a/sqrt{(x^$c+1)^3}");.

But, I will prefer to use the property derivative of Formula MathObject. Then
the main part of the problem will be

...
$f=Formula("x*sin(x^$b)^$a/sqrt(x^$c+1)");

Context()->texStrings;
BEGIN_TEXT
Find  \( f'\), given

\[ f(x) = $f \]

$BR $BR 
\( f'( x ) =\)\{ans_rule(100) \}

END_TEXT
Context()->normalStrings;

ANS($f->D()->cmp());
...


Best,

Edwin F.
