Re: Oh,Oh,Oh,merry analysis!!!

hi bobbym

well i would suggest you take the first 5 terms of the mclaurin's polynomial expansion and put in -0.1 instead of x.

Re: Oh,Oh,Oh,merry analysis!!!

HI anonimnystefy;

That would not get the correct answer.

Did we not start with a -.1?

Re: Oh,Oh,Oh,merry analysis!!!

Hmmm, have we squeezed all the juice out of the last question? I think not. Are 5 terms really necessary? Could you have provided a sharper bound then the Big O bound that wolfram provided?

Hi anonimnystefy;

Can you do a little better than the answer provided by using Big O?

Re: Oh,Oh,Oh,merry analysis!!!

Experimenting is okay. Did you try less terms for that truncated series?

Re: Oh,Oh,Oh,merry analysis!!!

hi bobbym

for 4 terms i found the abs. difference of about 4*10^(-6)

What was the highest power in your truncated series?

hi bobbym

Re: Oh,Oh,Oh,merry analysis!!!

Then what do you say about whether or not we can use a smaller series?

Re: Oh,Oh,Oh,merry analysis!!!

well we can,but only on experimental basis.if you were supposed to find the least number of terms you have to take,without that kind of calculation,then i would suggest using Big Oh notation.

btw,what is the name of the problem associated with this image:Veliki%20zadatak.gif

i know that the literal translation from Serbian is "The Great Problem"

Re: Oh,Oh,Oh,merry analysis!!!

Hi;

Beats me what that is?!

Yes, I would say we should stick to the Big O estimate here. So good work!

lots of parallel lines with those four circles.
Looks complicated.
Did you need to solve it?
