Yago schrieb: Uwe, in the page 2 you have on top an specific trigonometric example (Blancos) without brackets.

And more, when I say that the brackets are no necessary is because LaTeX add a little space between the function and his argument. So the reality is that LaTeX don't type, cos2vt but, cos 2vt with a little more space after "cos" and this is very comprehensive for everybody. This is nevertheless against the possibility to omit the braces only for 1 or 2 characters in the argument as defined in the norm. Don't you own a math or physics book or at least a school book? There you ca see how it is done. Please don't mention me the Wikipedia because this resource isn't at all a "canon" for nothing. The Wikipedia is the most impartial resource you can find. When you think there's something wrong you can correct it and cite other resources like books and norms. And furthermore, as everybody is writing it, mathematicians, as well as engineers, physicists, etc., the typesetting follows the common rules to avoid misunderstandings. (You are a military officer and know that most conflicts arise only out of misunderstandings.) regards Uwe

Re: Vertical spacing of matrices
Uwe thank you any other time for your comments, but I think you are wrong about the strict rules to typeset formulas, at least in the trigonometric formulas. For example when you say, (when the "sin" would not be upright, it would even mean s*i*n*1/2) you don't remember the "lineal functions" (archs) in a circle that are typed with the first letter upright, like this: Sin AM without brackets; a little more space between "Sin" and "AM" is all that it is needed. The trigonometrical functions are the lineal functions in a circle with the radius equal to the unity of mesaure. Then: Sin AM/R=sin a (R = radius) where "a" is the angle that subtends the "AM" arch. And also in this case that suffits the space between "Sin" and "AM/R" and "sin" and "a" to understand correctly the formula. And more, in the trigonometric formulas the strict notation "sin(a)" is normally not used but "sin a", like "sin 2a", "sin (A+B)" and so on, and I think that there aren't confussion about this. And if you type this formulas in LaTeX math mode an aditional space is added between the function and the argument. If you want to search a little that exists more secondary circular functions (due to spanish mariner Mendoza) not used today named "Sin v AM" (Seno verso), "Cos v AM" (Coseno verso), and also "Ver AM" (Verso of AM) or "Cov AM" (Coverso of AM) and "Sub v AM" (Subverso of AM). Without brackets.

There are strict rules in math how to typeset formulas. sin1/2 means sin*1/2 (when the "sin" would not be upright, it would even mean s*i*n*1/2) So "sin" is in your typesetting a variable or an operator but not a function. A function has to have an argument. For arguments round brackets are used: sin(0.5(a+b)) When you have several levels of brackets it is allowed to use brackets for the outer ones: sin[0.5(a+b)] although this is quite unusual. Normally one uses larger round brackets for the outer level and smaller ones for the inner level as explained in LyX's Math manual. Reading sin1/2(a+b) I first thought that you mean sqrt(sin(a+b)) although the 1/2 would then have to be set as superscript. You definitively need a bracket behind sin and the like, no matter where you are working.

Uwe is right: mathematicians all agree on the typographical rules for typesetting and writing mathematics so there will be no ambiguity in communicating. But when the communication takes place within a closed world, like our navel military formula, I suppose that world can get away with having its own rules, for brevity say. Bruce

Re: Vertical spacing of matrices
Uwe, thank you very much for your comments about my reply to Luca. In my case I have finished a book about trigonometry with 386 pages and obviously there are a lot of formulas and his deduction. All my problem with the method that I sended is reduced to copy and paste for the tables and matrices with too much rows. Respect to your second kindly comment, in the Spanish Navy Naval Military School (I am Commander in the Spanish Navy, Hydrographer) the brackets are omited in the notation to the half addition or difference of trigonometrical functions because the formula, sin1/2(A+B) in purity is the product of sin1/2 (I suppose in radians) and the addition of the angles A and B (also in radians). But in astronomical navigation this has no sense when we use, normally, the Delambre Analogies for the position triangle calculus, so we omit the brackets.
