%please help me find the values of l and m : where func should be maximum
syms l m;
w1= 981*l^(2)*(2-l)^(2)+(490.5*l*(2-l-m)*(-2*l^(2)-(m^(2))+(4*l)+(4*m)-(2*l*m))/2);
%
%
%
%
w2= (-981*l*(2-l-m)*(2*l^(2)+m^(2)+(2*l*m)-(4*l)-(4*m)/2)+(490.5*(l+m)*(2-l-m)*(-2*l^(2)-2*m^(2)+(4*l)+(4*m)-(4*l*m))/2));
func = (2*w1+w2)/(2*w1^(2)+w2^2);
eqn1 = diff(func,l)
eqn2 = diff(func,m)
% sol= solve(eqn1,eqn2,'l')
sol = solve(eqn1,eqn2)
lvalue = double(sol.l);
mvalue = double(sol.m);
