Spacing and colon … again

[smart_10357]

I have two questions:

1. Page 328 Question 29. Is there a space needed after the sin (superscript)-1 and the open parenthesis?
2. Page 340 Questions 30 and 41. Please note the 3:4:5. I don't think those are ratio colons. So are they treated as colons?

Hi. Thank you for asking these important questions.

Regarding question 29, yes, a space must precede the open parenthesis. The 2007 update to Section 119.a of the Nemeth Code says this: "A space must be left after an unmodified function name or its abbreviation. If the function name or its abbreviation carries a superscript, subscript, modifier, or other braille indicator, the space must follow the superscript, subscript, termination of modifier, or other braille indicator."

Regarding questions 30 and 41, 3:4:5 is a ratio. It means that the side lengths are in the ratio of 3:4:5.
