-# Trigonometrics are classified as many others are, they are first checked to see if they are non-atomic, and then the first element is checked, with the following being valid symbols:
|
|
|
-# - ~sin~
|
|
|
-# - ~cos~
|
|
|
-# - ~tan~
|
|
|
-# - ~csc~
|
|
|
-# - ~sec~
|
|
|
-# - ~cot~
|
|
|
+Trigonometrics are defined as non atomic expressions that are two elements long, for which the first element of the expression is either ~sin~, ~cos~, ~tan~, ~csc~, ~sec~, or ~cot~. For each of these there is a classification seperate from the generic ~trigonometric~ classification.
