The math evaluation supports trigonometry equations,
The evaluation of trigonometric functions by default is in radians, e.g. sin(\pi/2) == 1, but it can be switched to degrees using the Special Handling Options:
Special symbols like π can be entered via LaTex, e.g. \pi or via the keypad.
There is a custom keypad with the most common Trig related keys can be attached to the questions. Go to the Advanced Options to select the keypad, and then navigate down the left-hand side:
In addition, there is a more comprehensive set of keys in the full keypad.
Angle operations understand the equivalence of forms such as \angle ABC = \angle CBA
B is the common vertex and arms with A and C can be reversed.
