2 Input Ranges

Function		Input range for real				Internal	Precision	Notes
		number solutions				digits
sinx		(DEG) x < 9 ⋅ (109)°					As a rule,	However, for tanx:
						15 digits	precision is	x ≠ 90(2n+1): DEG
cosx		(RAD) x < 5	⋅	10	7π
					rad		±1 at the	x ≠ π/2(2n+1): RAD
tanx		(GRA) x < 1 ⋅ 1010grad
							10th digit.*	x ≠ 100(2n+1): GRA
sin–1x		x < 1
cos–1x						"	"
tan–1x		x < 1 ⋅ 10100
sinhx		x < 230.9516564						Important!
coshx								• sinh and tanh become
								singular points when x = 0.
						"	"	In this vicinity, errors
tanhx		x < 1 ⋅10100						become cumulative and
								accuracy deteriorates.
sinh–1x		x < 1 ⋅ 10100
cosh–1x		1< x < 1 ⋅ 10100				"	"
tanh–1x		x < 1
logx		1 ⋅ 10–99< x < 1 ⋅ 10100				"	"	• Complex numbers can be
Inx								used as arguments.
10x		–1 ⋅ 10100 < x < 100
e	x	–1 ⋅ 10100				"	"	• Complex numbers can be
		< x < 230.2585092						used as arguments.

x0 < x < 1 ⋅ 10100

x2	x < 1 ⋅ 1050	"	"	• Complex numbers can be
				used as arguments.
1/x	x < 1 ⋅ 10100, x ≠ 0
		"	"	• Complex numbers can be
3 x	x < 1 ⋅ 10100
				used as arguments.
x!	0 < x < 69
