Im having trouble finding a general formula for the nth term for the sequence {1, 1/2, -1/6, -7/24, 1/24, 7/48, -19/336, -503/4480, 17257/362880, 12913/145152,...} if one exist so far I am guessing that n! has something to do with it a hint would be super cool!

Did you try the alternating series test?

More feedback great! Class starts next monday and I am really excited thanx agian!

Im already planning a strategy for next semester. I think I am going to spend more time reading the books and thinking about the laws and theorems; Rather than working problem after problem like last semester. Great feedback! :-p

Thanks I think I am going to start reading my physics book right now!

hey everyone Im currently looking at my white board. I can see ghosts of Riemann sums not fully erased. I call them ghost because they scared me yesterday when I almost forgot how to work one! Wait I think I see something emerging from the dark depths of my book shelf...oh my godsh its my...

Now I am confused, would this work... \frac{d}{dx} \int f(x)dx= f(x) :rolleyes:

yes, the calculation you may have made a minor error 0=3a(4) + (4)b + c c= -12b - 4b yes c would equal zero according to this statement but i think you meant c=-12a - 4b

ok b does equal 0 but what about c

but does a=1/2

I would start by differentiating what you have.

I now understand thanks so much hall.

Yes but I am trying to solve it using differentials which is what I am struggling with

Can't seem to set this problem up Suppose a tree grows at a yearly rate equal to 1/10 of its height. If the tree is 10 ft tall now, how tall will it be in 5 years? dy/dx=x/10 y=(x^2)/20+c Im almost guessing this is right so far, if so will the 10ft be my constant?

If you want to be an electrical engineer your going to need to put in a good effort and a lot of focus. You should also research electrical engineering too so you really know what its about, don't guess. If you do go into the military and then forget stuff it shouldn't take long to relearn...
