You know what guys, I'm not happy with how things have gone with respect to the mission requirements. I'm going to start over and get a new assignment. That basically means a re-sit, but I don't feel good about this frankly piss poor work that I've done. Better to do things again and well than...
Sorry, "the linear part" of the lift-drag polar was the wrong thing to say. I meant that before it starts veering off to the right, I would like it to resemble a vertical line so there would be a similar low drag coefficient at most lift coefficients.
I'm sorry if my problem is confusing, the half-assedly put together nature of this assignment of mine is clouding my mind with questions and uncertainties. I'm sorry for posting this here as well, will do better next time.
Regarding my goals in the re-design of the airfoil - I've decided to...
Hello awesome science people.
I am a an aerospace engineering student and I am currently engaged in completing an assignment regarding a fictional re-design of the wing on a DeHavilland Twin Otter. I do have some difficulty though, since suddenly I have to independently manage to think about...
Thank you all for the help, I think I have the technique on my toolbelt now and it's properly calibrated. It just seems the necessary integration is mostly very difficult.
NewtonianAlch, jokes are all I can offer in return. Also, manbreasts. But those aren't very noteworthy so I'll stick to the...
But I can't integrate the solutions. The integrals are too hard and I don't see how they would become any simpler. The solution itself according to the undetermined coefficients method is pretty simple. I feel like flipping the table, opening the windows and yelling prophecies in tongues to the...
I know what you mean and I've already done that. As I said, I know how to find the particular solution using the method of undetermined coefficients, as you suggested. However, my quarrel is with the method of variation of parameters. I don't care for the solution as much as I want to use the...
Thanks for the alternative, Dick, but I know that I could use the method of undetermined coefficients, I'm just asked not to. My goal here is to correctly use the variation of parameters and to know that technique too.
I have to apologize in advance in case I violated some rule, since this is a first post. Also, it is 5 AM here and it is quite possible that I'm dreaming of posting this instead of actually doing it. Good night.
Hey ya'll!
This is the equation under discussion:
y'' - 2y' - 3y = x + 2
I'm asked to use the method of variation of parameters to determine a solution for this differential equation, but I reach a point where my the equations just look too ridiculous to continue.
The point I have in...
