Hello,

Find dy/dx by implicit differentiation.
tan^-1 (x^2y)=x+xy^2

I can find no documentation that it is possible in MATLAB (as much as I like it).
See this Wolfram Alpha page for the correct solution.

Example
syms y(x) DY
eqn = acot(x^2+x*y) - asin(x+y) == y^3-x;
dy = diff(y);
deqn = diff(eqn,x);
Deqn = subs(deqn, dy, DY);
DYsol = simplify( solve(Deqn, DY) );
disp(DY == DYsol)
