I want to solve 4 nonlinear equation using maple. I want to find many roots of this 4 nonlinear equation.

I have no idea about initial condition so I use 4 for initial condition. my program is as follow:

f1:=nonlinear equation1(include variable q1,q2,p1,p2);

f2:=nonlinear equation2(include variable q1,q2,p1,p2);

f3:=nonlinear equation3(include variable q1,q2,p1,p2);

f4:=nonlinear equation4(include variable q1,q2,p1,p2);
