It would be #(5pi)/6# as #arctan# and #tan# camcel out.

Explanation:

#Tan# answers the question: what ratio is there between the opposite and the adjoining side when the angle is #(5pi)/6#

#Arctan# answers the opposite question: what angle belongs to a certain ratio of opposite and adjoining sides.

#tan# and #arctan# are opposing operators, comparable to square and square root, or multiplication and division. They cancel out each other.
