In a way yes, but only acos, asin, & atan are described as the arc function. acot, acoth, acosh, atanh, & asinh are all described as the inverse function in the help. I think more people are familiar with the term "inverse" than arc.
Perhaps, I should give up my hope to use less words and just include both terms.
I agree with you in eliminating words, and being short, succinct, however, sometimes some verbiage is required to have some people understand that inverse, arc, and, -1 may refer to the same but that -1 may not always be interpreted as 'raised to' when it means "inverse' . Did I say that correctly?
