i've noticed you haven't posted in the thread. any ideas? I've asked around from a few guys I know and I can't seem to figure this out.

A question, does anyone here actually know how to solve it? Just out of curiosity guys and girls.

Yeah don't worry about it. I think posting here has just confused me more with everyone saying differing things. Ill ask a friend or something. Thank you for the effort though.

I can't seem to pinpoint where the error is. I'm sure the cos reads cos(2t). I'm probably making the simplest of errors. I'm still unsure of what I would do with the next sum though. Are we talking pi/4 for t where they're equal or?

You have got that right, granted I solved the general representation of the Series correctly. One thing is that n=1, you have n=0 there.

Not sure. The coursework doesn't mention using representations to solve series'. That's why I'm a little confused. I reworded it all to eliminate confusion (hopefully). Thanks for responding.

okay i'll make note of that thanks a lot for your help pasmith, it's been much appreciated.. do you mind if i shoot a few more maclaurin's your way in the future if i have an issue? possibly via PM?

why would you need to show that it's less than 2 though? i mean of all the numbers to pick, if you didn't know the answer, why would you pick 2?

i'm going to beg lol

No ideas anyone?

sub in 1 i guess since it's inclusive? i still don't get however how you ascertain that R3(x) is less than 1/12th

I did do that.. however I can't seem to procure the answer given in the text of |R3(x)| < (1/12) as sinh(1) < 2 I can't make sense of that.

don't look at it that way divide each term by the highest power variable and take each portion of the equations limit, separately. a quick way of doing it is to take a ratio of coefficients of variables in this case of an

Homework Statement The question asks to estimate the remainder on the interval |x|≤ 1. f(x) is given as sinh(x). I solved the polynomial P3(x) = x + (1/6)(x3) I then went ahead and solved R3(x) up to the point shown below. R3(x) = (sinh(c)*x4)(1/24)I then don't know how to go about...
