I am transcribing a math book in Nemeth. Because I am not "mathematically" skilled in Trigonometry, I am not sure of the correct way to braille a number that immediately preceeds a function abbreviation. Should there be a space between the number and the abbreviation or should there be no space. Print shows a space, but everything I can find shows no space. Nemeth Code, Intro. to Braille Mathematics, the internet, all show the preceding number and the function without a space. Just not sure if I should follow print, or if it is "assumed" that the number and function should be brailled without a space. Thanks in advance.
Print copy often spaces terms and symbols in an equation or expression. In braille we follow Nemeth Code spacing rules. Do not space between the numeral and the function name or abbreviated function name which follows. A space is required following the function name/abbreviation and its modifications, if any, as explained and illustrated in the Nemeth Codebook, Sec.119.
