Notes on mathematical functi...Implementation notes:<br />Notes on mathematical functions<br /><br />Note: ^ denotes the exponentiation operator, sqrt is the square root function, acos the arc-cosine (or inverse cosine) function and asin is the arc-sine function. If asin or acos are unavailable they can be implemented using the atan2 function:<br /><br />acos(x)=atan2(sqrt(1-x^2),x)<br /> acos returns a value in the range 0 <= acos <= pi<br />asin(x)=atan2(x,sqrt(1-x^2))}<br /> asin returns a value in the range -pi/2 <= asin <= pi/2<br /><br />Note: Here atan2 has the conventional (C) ordering of arguments, namely atan2(y,x). This is not universal, Excel for instance uses atan2(x,y), but it has asin and acos anyway. Be warned. It returns a value in the range -pi < atan2 <= pi.<br /><br />Further note: if your calculator/programming language is so impoverished that only atan is available then use:<br /><br /> asin(x)=2*atan(x/(1+sqrt(1-x*x))) <br /> acos(x)=2*atan(sqrt((1-x)/(1+x))) x>=0<br /> =pi - 2*atan(sqrt((1+x)/(1-x))) x<0<br /><br /> atan2(y,x)=atan(y/x) x>0<br /> atan2(y,x)=atan(y/x)+pi x<0, y>=0<br /> atan2(y,x)=pi/2 x=0, y>0<br /> atan2(y,x)=atan(y/x)-pi x<0, y<0<br /> atan2(y,x)=-pi/2 x=0, y<0<br /> atan2(0,0) is undefined and should give an error.<br /><br />Another potential implementation problem is that the arguments of asin and/or acos may, because of rounding error, exceed one in magnitude. With perfect arithmetic this can't happen. You may need to use "safe" versions of asin and acos on the lines of:<br /><br /> asin_safe(x)=asin(max(-1,min(x,1)))<br /> acos_safe(x)=acos(max(-1,min(x,1)))<br /><br />Note on the mod function. This appears to be implemented differently in different languages. Mod(y,x) is the remainder on dividing y by x and always lies in the range 0 <=mod <x. For instance: mod(2.3,2.)=0.3 and mod(-2.3,2.)=1.7<br /><br />If you have a floor function (int in Excel), that returns floor(x)= "largest integer less than x" e.g. floor(-2.3)=-3 and floor(2.3) =2<br /><br /> mod(y,x) = y - x*floor(y/x)<br /><br />The following should work in the absence of a floor function- regardless of whether "int" truncates or rounds downward:<br /><br /> <br /> mod=y - x * int(y/x)<br /> if ( mod < 0) mod = mod + x<br /><br />Sign Convention<br /><br />As stated in the introduction, North latitudes and West longitudes are treated as positive, and South latitudes and East longitudes negative. It's easier to go with the flow, but if you prefer another convention you can change the signs in the formulae.Just like a guyhttps://www.blogger.com/profile/14680468025321981540noreply@blogger.comtag:blogger.com,1999:blog-1956851062928470828.post-78597613760951679862010-05-18T18:37:41.692-05:002010-05-18T18:37:41.692-05:00dear TRS: how do you invert the circle of radius s...dear TRS: how do you invert the circle of radius sqrt(41) centered (5,0) through the circle of radius sqrt(21) centered at (-2,0).<br /><br />These questions are plaguing me.ehttps://www.blogger.com/profile/04376537400767851942noreply@blogger.comtag:blogger.com,1999:blog-1956851062928470828.post-83520890545398422922010-05-18T16:52:48.488-05:002010-05-18T16:52:48.488-05:00I will think deeply on the matter and make an appr...I will think deeply on the matter and make an appropriate contribution.bonnehttps://www.blogger.com/profile/18233228445664358396noreply@blogger.comtag:blogger.com,1999:blog-1956851062928470828.post-4537789521887398902010-05-18T16:21:46.255-05:002010-05-18T16:21:46.255-05:00Well, the next edition will be coming out sooner r...Well, the next edition will be coming out sooner rather than later, so if you'd like to contribute some more questions...Just like a guyhttps://www.blogger.com/profile/14680468025321981540noreply@blogger.comtag:blogger.com,1999:blog-1956851062928470828.post-60263767910100598482010-05-18T16:18:16.961-05:002010-05-18T16:18:16.961-05:00Well if you had warned me, I could have provided a...Well if you had warned me, I could have provided a whole slew of useless questions.

From the aforementioned wiki:<br /><br />The original Hungarian name of the town of origin was Szatmár. The name appeared at first in a document written in 1213 in the form "Zotmar". Originally it was derived from a personal name. The Romanian name was first Sǎtmar, differing only in orthography from the Hungarian one, but in 1925 was officially changed to Satu Mare. That version means "large village," with the Romanian Satu ("village") deriving from the Latin fossatum, while Mare means "large" in Romanian.[citation needed]<br /><br />There is a well known folk etymology, repeated both among members of Satmar itself and in outside literature about the group, that Satu Mare actually meant "Saint Mary." Many Hasidim, occasionally including Reb Yoel himself, referred to the town as "Sakmar" to avoid use of its allegedly "pagan" name. The folk story notwithstanding, the vast majority of hasidim now use the original Hungarian name "Satmar".<br /><br />le7: What!Just like a guyhttps://www.blogger.com/profile/14680468025321981540noreply@blogger.comtag:blogger.com,1999:blog-1956851062928470828.post-69837587770170537782010-05-18T06:37:23.598-05:002010-05-18T06:37:23.598-05:00Halelu is the only Lipa song I like.Halelu is the only Lipa song I like.le7https://www.blogger.com/profile/08982516647753962603noreply@blogger.comtag:blogger.com,1999:blog-1956851062928470828.post-88244063465978118602010-05-18T02:11:17.848-05:002010-05-18T02:11:17.848-05:00I don't wish to come across as a "zealot&...I don't wish to come across as a "zealot", but surely the name doesn't need to be "[..] Mary" (regardless if said writer wrote such) - <br /><br />just as you eloquently respond in a different fashion.<br /><br />To throw in an anecdote relating to TRS' former city (I heard it from a "landzman" of his):<br /><br />There was some plaque or the like for a dinner of Chabad Minnesota, which reviewed it by the Rebbe prior to its finished copy.
