328:: how does one, like myself, manually calculate these results? That being said, a year is simply one date to the exact same date a year later: example = June 12, 1965 to June 12, 1966. Sure, whenever you are doing calculations with dates / calendars, the issue of leap years and February 29th comes up. Nonetheless, that does not convolute or obfuscate my original question. The anomaly or ambiguity would lie in the algorithm, which is not my original question. In any event, the February 29th "issue" (if you will) will be negligible at best and will probably hardly ever surface. If it does, I would posit that it works like this: if we start out at February 5, 2004 … a year later will be February 5, 2005 – regardless of the fact that there is an extra day (Feb. 29th) wedged in there. In other words, in that case, the term "year" simply means 366 as opposed to 365 days. 538:(for "fun", I appreciate there are plenty of other ways to do this on a computer). The implementation continues until the value of the n term is below a certain threshold, at which point the algorithm returns; so I can count how many terms I need to evaluate for a given degree of accuracy. There are marked optimisations to be had in exploiting the symmetries of the sine function: identities that move values into the 0..2Ο€ range, and further that move those from Ο€..2Ο€ into 0..Ο€ make for marked improvements - clearly the series converges much faster in the 0..Ο€ range than for other values. I've coded a futher (trivial) symmetric optimisation that flips values in Ο€/2..Ο€ down into 0..Ο€/2, but that doesn't produce any improvement. Am I correct in thinking that the convergence of the Taylor series for sine between 0 and Ο€/2 is not much faster than between Ο€/2 and Ο€? -- 321:
equally unhelpful to have output that says "Adrien Brody is 29 years, 11 months, and 9 days old." The chart in the above link is formatted with an individual's age reported as Y years old and D days old. Thus, that is the format of the data output that I would like to receive. If the results are given simply in terms of D days old … or even in terms of Y years, M months, and D days old – that will not be useful to me. All of the websites that I have found give me the output in one of those two ways that are not helpful to me. I am looking for a website (or function in Excel) that will output the result in the format I need (age expressed as Y years and D days).
313:. As you see, that list includes the individuals’ ages. I am proofreading that list (and many others) and checking for errors. And I am also involved in several projects of a similar nature. Ultimately, there will be many, many, many ages that I need to compute – with the above link merely being an example. I certainly know how to calculate these figures manually. That is, I know the mathematical / numerical algorithm that will achieve the answer. However, because I have so many dates to calculate, I am trying to make the task easy / manageable / as painless as possible. I don’t want to manually do all this … I want a computer / calculator to do it for me. 6901:
the problem greatly by discarding the higher-order terms. Depending on the size of the perturbation and on the accuracy required and on the problem itself, we may wish to keep second-order terms as well (or more); but a great deal of applied mathematics works with a first-order approximation. We then apply the powerful machinery of linear algebra to the "linearized problem". This is such a habit that folks may forget that nature itself often
6897:, we can create a model of the reals extended with infinitesimals. In this approach, Ξ΄ is taken to be such a nonstandard quantity, a genuine infinitesimal, and the result of the subtraction and division is coerced back to a standard quantity. Another approach is to extend the reals with a quantity Ξ΅ defined to satisfy Ρ = 0, but Ρ ≠ 0. If this is used for Ξ΄, the higher-order terms automatically disappear. 118:
result is in the desired format)? (Question #3) In Excel 2007, I cannot seem to work with dates prior to 1/1/1900. That is, the date of January 1, 1900 -- and all subsequent dates -- are valid. Any date prior to that (December 31, 1899 and earlier) seem to be invalid dates that trigger an error message. Does any one know a way around this limitation in Excel 2007? Thanks. (

Well, not mistaken, but perhaps not interpreting terminology correctly. I understood "small" to mean "infinitesimal", but not that "produces no change" meant "produces change of second order or higher". If this is standard language in calculus, could you give some other examples of how "X happens" is

To avoid the vagaries of excel just put the years, months and dates in separate columns, say A1,B1,C1,D1,E1,F1 for (year1,month1,day1,year2,month2,day2), to find the number of years difference use G1=IF(B1<E1,D1-A1,IF(C1<F1,D1-A1,D1-A1-1)), the birthday will then be H1=DATE(A1+G1,B1,C1) if the

Before you rush off to finding a program that calculates what you want, you need to know what you want. It astonishes me how you have avoided answering a question that was posed twice.

So what will the answer be? 1 year, or 1 year and a day? 1 year and a day will be weird, as there is no date defined as 1 year after 2.29.05. Another peculiarity is that both 2.29.04 to 3.1.05 and 2.28.04 to 3.1.05

Also – back to Excel for a moment. It seems hard to believe that a behemoth like Microsoft would not allow us to account for dates pre-1900. Dates pre-1900 would be relatively common for various uses. (How many days was George Washington in office? How many days did the American Revolution or the

I wasn't sure what Help Desk to use for this question ... so I am going with Math (here). Given two dates, I want to be able to compute the amount of time elapsed between the two dates. So, for example, if I have May 3, 1962 ... and January 17, 1981 ... I want to know that the time elapsed between

The general idea of discarding higher-order terms has many practical applications. For example, we may have a physical problem where the full description is quite complicated. However, if we can write the effect of a small perturbation as a series of terms of increasing order, we can often simplify

Isn't this ambiguous? What is the amount of time, in your format, elapsed between March 1, 2003 and March 1, 2004? And what is it for February 28, 2003 and February 28, 2004? What about February 28, 2003 and February 29, 2004? And March 1, 2003 and February 29, 2004? And, finally, February 28, 2003

To quantify the effect: if you stop when your term drops below 2 in absolute value, then for x = Ο€ you will stop at x/29!, while for x = Ο€/2 you can stop "already" at x/23!. That is, indeed, not a big deal. However, for x = Ο€βˆ’3 you only need to go to x/11!, which is a considerable gain compared to

So, to address Lambian’s point - it is outside of the scope of the question. I am asking if there is a computer / calculator out there that will allow me to input two dates and receive as output the age I need. How this computer / calculator does this calculation is of no interest to me. So can

If you had bothered to try to answer Lambiam's questions, you would have found out the ambiguity\anomaly. The ambiguity is "what is the difference between February 29 2004 to March 1 2005?". The anomaly is that however you answer this question, you will get something weird. We can help you more if

I want to know whether LHS = RHS or not. As a background, R(p,q) is the Euclidean distance between points P and Q in a meshed unit cube (in all there are N = n^3 regularly spaced points), and x(p,q) is just x-component of the distance. Also, N can be arbitrarily increased, so that the points are

To be more specific: Let's use the first person on the list as an example. Adrien Brody is 29 years and 343 days old. So, if I entered the beginning and ending dates, I want that as my result. It is not helpful to me to have output that merely says "Adrien Brody is 10,935 days old." It is

There be dragons! As I mentioned in response to a question about associativity, floating point addition rounds to a fixed precision. If you add the terms from largest to smallest, the contributions of the small terms can disappear. Either add from small to large, or use something like the

you explain what do you need this for. As it is, I think your best bet will be to find the number of days (easy, there should be a function for this in excel) and divide it by 365.2425 - the quotient will be the number of years, and the remainder (rounded) will be the number of days. --
765:. Once again, it is up to you and your desired accuracy to decide if the difference is great. If what you're asking is about the largest term in the series (which bounds the greatest precision you can achieve with given internal precision), it is roughly 1.5 and 5, respectively. -- 211:
Then to find the numbers of days difference, you can use (forcing valid excel years) something like "=date(2007,B1,C1)-date(2007,B2,C2)" possibly +365 or +366 depending upon whether years are leap or not. Note that this isn't easy because, say your dates are from leapyear-feb-14 to

Is this right and if yes, as I'm sure it isn't conincidence that it is my previous answer times minus one, could I have arrived at it without doing any of this working, i.e. just using my first answer and the fact that the square of an imaginary number is minus one?
5625:
Yep, that's right. And to be honest, I have no idea if you can simply do that every time without doing it out... the fact that it's equal to x^4 might be why such a thing is the case, but to be honest I'm not entirely sure -- someone else will have to answer that.

inf (i.e., we consider all points in R^3), then shouldn't this "error" should keep decreasing with increasing n? The result for n = 2 makes sense because in that case, we have 8 points, which all have three neighbouring points "filled" and other three "empty."

Thanks but I'm an amateur mathematician so what you said about limits means little to me. I have heard about minimums, and maximums, existing at 'end points' before. Could you show me where to find out more about them? Thanks

birthday after 1900 you can then subtract I1=date(D1,E1,F1)-H1. For Feb 29 you can do it by hand, taking either Feb 28 or March 1 for non leap years. If you need to work pre 1901 then you'll need to correct for leap years.
