angle ¡ Overrides current angle mode setting to express angle in degrees
angle r Overrides current angle mode setting to express angle in radians
degrees ' minutes ' seconds ' Designates an angle as degrees, minutes, and seconds
angle 4 DMS Displays angle in degrees

sinh value Returns the hyperbolic sine of value
cosh value Returns the hyperbolic cosine of value
tanh value Returns the hyperbolic tangent of value
sinh L 1 value Returns the hyperbolic arcsine of value
cosh L 1 value Returns the hyperbolic arccosine of value
tanh L 1 value Returns the hyperbolic arctangent of value
