Accuracy
As a rule, accura-
cy is + 1 at the
10th digit.

Notes
However, for tanx:
|x|
≠
90(2n+1):Deg
|x|
≠ π
/2 (2n+1):Rad
|x|
≠
100(2n+1):Gra
Note: For sinh and tanh, when x=0,
errors are cumulative and accuracy
is affected at a certain point.
However, for tan
θ
:
|x|
≠
90(2n+1):Deg
|x|
≠ π
/2(2n+1):Rad
|x|
≠
100(2n+1):Gra
