+	-	*	/	^	abs()	int()	hev()
ln()	exp()	log()	sqrt()	sin()	cos()	tan()	cot()
asin()	acos()	atan()	acot()	sinh()	cosh()	tanh()	coth()

Type an expression in the upper text field (real arithmetic only). Evaluate shows the result in the field below. Clear deletes both lines. Functions and Constants display the functions and some physical constants the script knows about.
