this is a  kuhn tucker optimization problem, with a generic function with some properties v(0)=0,  it is  a  positive,  monotonic growing...
with this i can find an optimal...with pen and paper

eval is not me, I need to restrict parameters for range
such a <0

gracias

ok

equation := x^2 + a*x + b = 0;
eq1 := eval(equation, {a<0, b > 0});

eq2 := eval(equation, {a<0, b < 0});

eq3 := eval(equation, {a>0, b > 0});

eq4 := eval(equation, {a>0, b < 0});

but I can´t use <> with eval()

thanks and I found what I needed op (1,(1))

hablo español y me cuesta el ingles por eso no me explayo...

por ejemplo uso eval despues de solve usando label.

I can hardly speak Spanish and the English so I'm not elaborated...

for example using eval after solve using label

solve({(1), (2), (3), (4)}, {x,y})

solve(eval(x, (5)[1])=c, z)

to refer to the solution number 1 for the variable x.

now I want a similar method to refer to a parametric conditions solutions... ( () after and)

para hacer referencia a la solucion numero 1 para la variable x.

ahora quiero un metodo similar para referirme a las condiciones parametricas de una de las soluciones

piecewise(a < -(4*((-ce-pk)/b-(1/4)*(-ce-3*pk-2*ci)/b))*b, [{k <= (a-ce-pk)/b}], And((4*((1/4)*(-ce-3*pk-2*ci)/b-(-ce-pk)/b))*b <= a, a < -(4*((-ce-pk)/b-(1/4)*(-ce-2*pk-2*ci)/b))*b), [{k <= (1/4)*(3*a-ce-3*pk-2*ci)/b}], (4*((1/4)*(-ce-2*pk-2*ci)/b-(-ce-pk)/b))*b <= a, [{k <= (1/4)*(3*a-ce-3*pk-2*ci)/b}], []);

@acer Thanks, that needed
