When looking into using square root in the answer to a calculated type question, I could not find it in the list of php functions provided within the help given via the edit page for calculated questions. Therefore I ended up using "POW." It also called my attention the name "sprt" listed among the php functions provided by the help pop-up window. Finally I got time to get a PHP book from the library to look into what the heck that function was... I could not find any php function with such name, but I did find "sqrt" for the square root of a number.
Is this a typo in the help pop-up? Who can fix the typo in such case? What file needs to be accessed to do it so other instructors do go through the same problem?
Thank you for your help!
