can anyone one help me to download maple 6 ?

i want to plot these four functions in the same graphe f(x)=1/1+x^2 on the intervalle [0,1] also the second function the line curve that connects the two points(0,f(0)) and (1/3,f(1/3)), the third function the line curve that connects the two points (1/3,f(1/3)) and (2/3,f(2/3)), the fourth function the line curve that connects the two points (2/3,f(2/3)) and (1,f(1))

can anyone help me ?

can any one help me ? thank you

I want  to find the parametrs that verify the below inequalities at the same time:

beta*(v+u)>phi*(alpha+lamda+u+delta)

phi>beta

beta> (alpha+lamda+u+delta)

phi* (alpha+lamda+u+delta)>beta*(u+v+alpha),

question : find the values of u,v,delta,lamda,phi,beta,alpha such as all these parameters are in the intervall ]0,1]
