Hi. how can i plot this eq. to (qa-w)?
2502*cos(qa) - (6*w^2*cos(qa))/5 - (50873*w^2)/52500 + (123*w^4)/87500 - 357706/63=0
thank you

syms qa real
syms w
eqn = 2502*cos(qa) - (6*w^2*cos(qa))/5 - (50873*w^2)/52500 + (123*w^4)/87500 - 357706/63 == 0;
sol = solve(eqn);
sol = sol(isAlways(sol>0)); %4 solutions, 2 of which are complex, 1 is always negative for real qa
fplot(sol, [-pi pi])

Execute those in the command window after you run the code I posted earlier, and tell us what the results are. These are commands to help us debug the problem, not commands that will somehow fix the problem.
