Infinite Series Homework Help

Infinite Series is really difficult for me to understand...
Anyways I need help on #2-c and #4-c...
I know for number #4-c you use the Remainder Theorem but can someone help me understand how to use that please.
Thanks

But for 4c, apparently you use the 4th degree og f(x), which will equal (16x^8)/4!, plug in .6 for x, and it'll equal to .011, which is less than .02. I think 2c was addressed before, but I don't get why x=1/3 just because ln(5/2-1)=ln(3/2)

Oh yes, for 4c, x=1/2, or at least it appears that way because x=5/2, and since each x is subtracted by 2, it looks like it's 1/5. So from there, you get 1/2-1/8+1/24. Since 1/24 is less than 1/10, you add up the taylor polynomials proceding it, 1/2-1/8=.375. And by AST, the terms are converging tp zero. I hope this helps.
