**calculus-- need help desperately!**

The Taylor series about x=5 for a certain function f converges to f(x) for all x in the interval of convergence. The nth derivative of f at x=5 is given by f^(n) (5)= (-1)^n(n!)/((2^n)(n+2)), and f(5)=1/2. Write third degree Taylor polynomial for f about x=5. Then find the ...

Three identical resistors are connected in series. When a certain potential difference is applied across the combination, the total power dissipated is 18.0 W. What power would be dissipated if the three resistors were connected in parallel across the same potential difference...

**Calculus Derivative- Taylor Series?**

let f(x)= x/x-1 find f'(x) f ''(x) and a formula for f ^ (n) * x. I found the first and second derivatives but do not know how to make a general equation for this. I have not learnt the Taylor or Maclaurin Series either. Thank you.

Where did the exponential series come from? 1 + x + x^2/2! + x^3/3!... Where did that number come from? and how is it used to get the trigonometric series?

**Math**

Consider the following series: 1,2,3,4,5,10,20,40....which starts as an arithmetic series? ...but after the first five terms becomes a geometric series. Prove that any positive integer can be written as a sum of distinct numbers from the series. I know how to do the base case

**please help with calculus- thank you!**

Is this correct? determine if absolutely convergent and convergent 1. the series from n=0 to infinity of ((-1)^n)/n! I said it was abs. conv, and therefore conv 2. the series from n=0 to infinity of (-1)^n/(the square root of (n^2+n+1)) I said ratio test was inconclusive so ...
