    Using Fourier series to evaluate sum of 1/(4n²-1)

    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.

    Using Fourier series to evaluate sum of 1/(4n²-1)

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

    Using Fourier series to evaluate sum of 1/(4n²-1)

    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.

    Using Fourier series to evaluate sum of 1/(4n²-1)

    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?

    Using Fourier series to evaluate sum of 1/(4n²-1)

    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.

    Using Fourier series to evaluate sum of 1/(4n²-1)

    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.

    Maclaurin remainder interval estimate

    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?

    Maclaurin remainder interval estimate

    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?

    Maclaurin remainder interval estimate

    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

    Maclaurin remainder interval estimate

    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.

    Why does the sum equal the limit when the series terms are positive?

    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

    Maclaurin remainder interval estimate

    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...
