Context Function Categories

The functions available to be used in student answers are controlled via the functions object of the current Context. See Answer Checkers and the Context for details about how to enable and disable these functions. This can be done either singly or by categories of functions.

The available function categories are the following:

Category	Functions Included
SimpleTrig	sin, cos, tan, sec, csc, cot
InverseTrig	asin, acos, atan, asec, acsc, acot, arcsin, arccos, arctan, arcsec, arccsc, arccot, atan2
SimpleHyperbolic	sinh, cosh, tanh, sech, csch, coth
InverseHyperbolic	asinh, acosh, atanh, asech, acsch, acoth, arcsinh, arccosh, arctanh, arcsech, arccsch, arccoth
Numeric	log, log10, exp, sqrt, abs, int, sgn, ln, logten
Vector	norm, unit
Complex	arg, mod, Re, Im, conj
Hyperbolic	all of SimpleHyperbolic and InverseHyperbolic
Trig	all of SimpleTrig, InverseTrig, and Hyperbolic
All	all of Trig, Numeric, Vector, and Complex

See pg/lib/Parser/Context/Default.pm for the definitions of all the functions, and pg/lib/Parser/Context/Functions.pm for the code that defines the categories.
