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–1x								"	"
tan–1x
