Welcome to the Papoose Lake UFO Reverse-Engineering Base, aka S4. As long as you keep everything here classified, we shall remain chill. Oh, and also welcome to OpenStudy. Enjoy your flight.
lol, to be honest i find this funny but don't really get it, maybe some context might make it clear. On topic, Did you finish the course? Pd. Thanks for the answer, is good to know i'm not solo :)
Well, stick around and you might understand later. =P And I believe I have went through a course that's at least similar to this. e.e And no problem. You can always count on someone to be alongside you on your quest to learn.
Hey, I just started this course too! How far are you now, because I could really use someone to study with :)
I'm just about to finish second session.
I started this the other day also :). I'm almost done with the third session.
I'm really bad at figuring out how to create a model, like what the changes are over time and what the variables are. Does anyone have any tips, is this something you just pick up over time and practice? Thanks
Actually the way we initially model is really simplistic, we're just asuming that a quantity of something is proportional to another quantity, so mostly of our models are y=kx, just like hook's law. But as soon as we get deep into the course we should be able to model more complex situations. If you want to get better at modeling you just have to think about a phenomen (be it physical or from economy, like the bank account example) and try to describe it, then you have to find which factors govern the development of your phenomen, now from this you could create your model, but it's likely you will find more than 3 factors so what you have to do now is make it simple by discriminating those who you consider has the less impact in your phenomen development. To be honest, the way you get used to modeling is by studying physics and chemistry, specially when you read the explanations about how did a science equations came up. Pd. I apologize if i didn't make itclear enough, i don't have many problems reading this language but i'm still learning to write it properly.
Thank you so much that was a really good explanation, I think I get it now, after studying complex numbers then coming back to modelling it made more sense. :) have you done any other MIT courses?
I did single variable calculus at the same i time i was taking it on university, but just went through half of it. I'm looking forward to finish this one now that i'm on vacation untill August 20th.
