Hyperbolic key
Press to use the trigonometric function keys (sin, cos, tan) as hyperbolic functions.
• sinh (z) = 1/2 (e
z
– e
–z
)
• cosh (z) = 1/2 (e
z
+ e
–z
)
• tanh (z) = sinh (z)/cosh (z)
Press to view hyperbolic sine (sinh).
Press to view hyperbolic cosine (cosh).
Press to view hyperbolic tangent (tanh).
Arc hyperbolic key
Press to use the trigonometric function keys (sin, cos, tan) as inverse hyperbolic functions.
Press to view inverse hyperbolic sine (sinh
–1
).
Press to view inverse hyperbolic cosine (cosh
–1
).
Press to view inverse hyperbolic tangent (tanh
–1
).
Decimal degrees (decimal hours) key
Degrees/minutes/seconds (Hours/minutes/seconds) key
Press to convert a number to:
• decimal degrees or to
• decimal hours
