Wow I don't understand how I overlooked that, I must have not been thinking or something because I did consider that case... Thanks for the help Ricky,

Hello everybody. This is my first post at this forum, and I am in need of some serious help for a question that I can't seem to figure out.

I can't solve this 1st order ODE: 3t^2 + 2t + y cos(ty) + (sin(y) + t cos(ty)) dy/dt = 0

The thing is that up until now we have learned how to solve non linear ODEs by substitution, recognizing separable equations, integrating factors, exact equations, and using Bernoulli's equation. None of these however seem to be of use for this equation, and this leaves me stumped.

Any help would be greatly appreciated,

C_ECE.
