Is the logarithm method used by Catholic lumberjacks for birth control?

HA, you spelled something wrong. OK, cheap shot, but a simple man (me) needs but simple victories. \n\nNow as to your question: There are no Catholic lumberjacks. A smattering of Protestants, Agnostics, and in previous years, Muslims. The Muslims were replaced by Druids do to the unfortunate mortality rate the Muslims incurred due to their prayer stance 5 times a day. While facing Mecca, on their knees, face down, they suffered an extraordinary number of injuries from falling trees, rolling logs and horny Protestants. \n\nThe Druids, however, proved to be well inclined to take up the slack, as it were. While it is true that they did worship the trees, reformed Druids (they pretty much stick to bushes) proved themselves to be a viable and energetic work force. \n\nThey were further encouraged by the EPA since it is common knowledge that Druids will not eat Spotted Owls.

The logarithm is the mathematical operation that is the inverse of exponentiation, so you were not wrong.\n\nFor  y = log(base b)(x)\nThe inverse of a logarithm is called an antilogarithm or antilog; thus, x is the antilog of y in the base b. \ni.e x = b^y\n\nSimillarly in a prticular case of natural logarithm (base e)\n\nFor  y = log(base e)(x)\nx is the antilog of y in the base e. \ni.e x = e^y.\n\nI hope, I answere your question.

First you need to know what logarithms are. (logs)\nAll numbers can be written as a power of ten.  These are logs.  \nUsing a base of ten, \nlog 100 = 2 (because 100= 10 x 10 = 10 to the power of 2)and \nlog 1000 = 3 (because 1000= 10 x 10 x 10 = 10 to the power of 3).  \nNumbers between 100 and 100 will have a log between 2 and 3.  You can find the power by pressing the log button on the calculator.  Often people use natural logs which are powers of e (2.71...). For these press ln\nAnti-logs are the original numbers that the logs represent. Anti-logging is the process of finding the number represented by the log.  These days you would use a calculator and press inv log.  \nFor example log 50 = 1.70\nantilog 1.70 = 50\nwhich is the same as 10 to the power 1.70 = 50.\nIn the olden days, 25 years ago, before calculators Logs were useful when multiplying large numbers. You would find the logs of the numbers and then add the logs, before antilogging the answer to find the result of the multiplication. By subtracting logs you can do division. \n\nNow, just get out the calculator. I haven't heard the term antilog for many years as you would better represent your working using log and then using powers.

y = (x mod 5) + 1.\n\nThough that does seem a bit like cheating :)

You can also use the log function.

Log is known as Common or Briggsian Logarithm while ln is Napierian or Natural Logarithm.\nThe log is what is commonly used while the ln is usually used when the irrational number e appears in the equation.This will simplify the calculation.\nHowever, they can be used interchangeably:\n\nlog x = ln x / ln 10   \n\nln  x = log x / log e

no this is how to work it out. I am assuming you know how to take the logarithm of a coplx number and find the modulus and argand of it.\n\ni^i = e^(logi^i) = e(ilogi)\n\nnow log i = log|i| + i(argi)\n= 0 + iπ/2 + i2kπ\n\nwhere k is an integer\n\nso substituting this is\ni^i = e^(i(iπ/2 + 2ikπ)\n= e^(-π/2-2kπ)]\n= e^(π[-1/2-2k])

There's a book called the Art of Natural Family Planning.  I think that's what it is called.  But it teaches how to tell when a woman is ovulating from taking her temperature, and other signs to look for to know the fertile times. It's a great method.  I did not enjoy the pill.  I was moody all the time and I didn't know what was going on with my body. This other method is great.  I know what is going on in my body.  There's more control.  Don't do anything permanent.  SOmeday you might want kids.

The secret is to understand some of the rules of logarithms and adjust translate the numbers to make your lob easier.\n\nThe rules:\nlog(a*b) = log(a) + log(b)\nlog(a/b) = log(a)- log(b)\nlog(a^n)=nlog(a)\n\nIf I understand your problem:\n\nx= [(86400)*sqrt(365.25)]/[ (.079)^11]\n\nso log(x) = log [.....]\n\n     = log(86400)+log(356.25^.5) - log(0.79^11)\n     = log(86400)+.5*log(356.25) - 11*log(0.79)\n\nuse log tables to get the logs and add them up to get the log of x.  Use the tables again to find x.\n\nYou can make other approximations, i.e., 356.25 is close to 19^2 (=361)\nand 86400 is close to 300^2 (=90000) and continue from there.  \n\nHope that helps.

Logarithms, when applied to imaginary numbers can have many results. This is because exponentiation, when applied to imaginaries, is defined as a trig function:\n\ne^(ix) = cos x + i sin x\n\nSo, the logarithm is an inverse trig function. And we know inverse trig functions can have many results. ln e^(2 pi i) can be 2 pi i, but it could also be 0, or -2 pi i, or basically any ix where (cos x + i sin x = 1). In this case 0 fits with the real logarithm on the right side, since ln(1) = 0.

That makes absolutely no sense at all.\n\nWithdrawal method is a risky often poor method of birth control and that is it.  Dry skin and forgetfulness are totally unrelated.

Adding logs is the same as taking the log of the two numbers multiplied. \nSubtracting the logs is the same as taking the log of the ratio (left number divided by the right number).\nlog (a) 15 - the log (a) 3 = log (a) 15/3 = log (a) 5.

The Church forbids use of contraception (not that Catholics in the US care)  AS for Family Planning, they support the use of Natural Family Planning, most famously the use of Rythmic timing (having sex when the odds are better or worse that the woman is ovulating).

The Bible says that whatsoever the Church binds upon earth is bound in heaven. This obviously includes the immorality of artificial contraception. The "rythym method" hasn't been used by anyone in over 40 years. Modern Natural Family Planning methods are extremely effective, and morally sound. And interestingly, the divorce rate among couples who use such methods is 3%, compared to 40% among users of immoral means of contraception, and 75 to 80% among couples who abort a child. Sin never makes anything better.\n\nhttp://www.bygpub.com/natural/natural-family-planning.htm\n\n.
