Hi. I'm having a problem getting questions involving ln()and abs() operators to evaluate correctly. For example, when creating maple graded questions, I set the correct answer to say ln( abs( x^3 + 12 ) ). So when the student enters this answer in text mode, everything is fine. In symbolic mode if ln( |x^3 + 12| ) is entered everything is fine, however, if ln|x^3 + 12| is entered, maple TA says wrong. The lack of parenthesis gives a wrong answer. Does anyone know how to make maple TA more tolerable in this situation to evaluate ln|x^3 + 12| as a correct answer? Thanks
