`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.`

Regards Yago.

Yago schrieb:Without new commands, for matrix you can use the command \vspace like inthe attachedd file that presents the Delambre Analogies in a matrix.This is indeed also a solution but might need more time when you have manyrows and columns.Looking at you file I noticed that you are using terms like cos1/2(A+B) This is incorrect typesetting. The correct one is this: http://mathworld.wolfram.com/GausssFormulas.html (the 1/2 in in the argument of the function)regards Uwe
