I'm trying to solve a system of 4 non-linear equations using the function solve with the following commands:
eqn1:=a^2-b^2-(7.638e5/c^5)=0;
eqn2:=(-4.919e6*a^(-0.7698))-2*a*d=0;
eqn3:=(-5.541e7*b^(-1.2302))+2*b*d=0;
eqn4:=5.76e7*c^0.6-3.819e6*d*c^(-6)=0;
answer:=solve({eqn1,eqn2,eqn3,eqn4},{a,b,c,d});
It's taken 860 secs and still counting. When should I give up or suspect an error in my formulation?
