cubefunc

This program will apply a chosen function to the input cube

This program will apply the chosen function to the input cube. The following functions with their corresponding restrictions are available: NOTE: Trig functions requiring angles as the input must be in radians. 
    	FUNCTION       RESTRICTIONS
	cos (x)
	sin (x)
	tan (x)        x cannot equal: 90, 270, -90, -270,
                                       pi/2, 3pi/2, -pi/2, -3pi/2
	arccos(x)      -1.0 < x < 1.0
	arcsin(x)      -1.0 < x < 1.0
	arctan(x)
	1.0 / x        x cannot equal 0.
	sqrt (x)       x must be greater than or equal to 0.
	10 ^ x
	e ^ x
	x ^ y          x is the input cube, y is an input constant
	log (x)        x > 0
	ln (x)         x > 0
	abs(x)
