Talk:Documentation/Calc Functions/ACOSH

SF Review Comments

(1) Do we know why the ODFF states that this function should calculate the "principal value"?

(2) The last line of the example table mentions ACOS rather than ACOSH.

(3) Should the Arguments section state the error that arises for an out-of-range value?

(4) In the Returns section, I might change "that is the number" to "that is the value" because the word "number" appears too often!

(1) We need to figure this out although logically it sound wrong correct me if thats not true but principal value is between _pi and pi whereas we can get infinity here

(2) Corrected

(3) I have added it in additional details just like other functions to follow format also in functions before I have done the same it appears that first one or two I made this error all ahead have format as per now

(4) Done

OH-> Steve

(1) Correct me if I'm wrong but since COSH is an even function (COSH(negative)= COSH(positive)) the ACOSH function could also return the negative value, hence the "principal value" to specify the positive value.

Time to remove the blue box on the top.
