Hey guys, I'm in System Dynamics and have been given a fairly fundemental problem to work on.
It states: can also be written . It then instructs me to derive equations for C and D in terms of A and B. I know this is pretty fundemental, I also know that , and but I do not want to confuse deriving an equation with substitution.
I'm not looking for an answer or anything like that, I just need someone or several people to put me on the right path. I'm not quite sure where to start. Thank you.
Ok, thank you for the head start. So now I have just a couple of questions:
1.) Because these equations are based on the displacement of a point, should I be looking at taking a derivative?
2.) Since he's giving me the values for two variables and there's two equations, is this going to be a two equations, two unknowns deal?
Thanks for your help.
In general a function of real variable can be devided into its 'even part' and 'odd part' as...
(1)
... where...
(2)
Now if we have...
(3)
... and if we have...
(4)
Using (1),(2),(3) and (4) You are able to pass from A and B to C and D and vice versa without diffculties...
Kind regards
Based on what you have asked above you need to go and see your lecturer or tutor and check that you have the required background in maths to do this course and/or see what revision or catch-up resources are available to bring you up to speed on the maths background you need.
