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:
cosx			(RAD) x < 5 ⋅ 107πrad	15 digits	precision is	x ≠ 90(2n+1): DEG
tanx			(GRA) x < 1 ⋅ 1010grad		±1 at the	x ≠ π/2(2n+1): RAD
					10th digit.*	x ≠ 100(2n+1): GRA
sin–1x			x < 1
cos	–1	x
				"	"
tan–1x			x < 1 ⋅ 10100
sinhx			x < 230.9516564			Important!
coshx						• sinh and tanh become
				"	"	singular points when x = 0.
tanhx			x < 1 ⋅10100			In this vicinity, errors
						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
