2 - 10 Trigonometric / Inverse-Tri. functions
• SRP-280 / SRP-285 provides standard trigonometric functions and
inverse trigonometric functions - sin, cos, tan, sin
–1
, cos
–1
and tan
–1
.
See Example 31.
(Note) : When using those keys, make sure the calculator is set for the
angle unit you want.
2 - 11 Hyperbolic / Inverse-Hyp. functions
• SRP-280 / SRP-285 uses [ 2nd ] [ HYP ] to calculate the hyperbolic
functions and inverse- hyperbolic functions - sinh, cosh, tanh, sinh
–1
,
cosh
–1
and tanh
–1
.
See Example 32.
(Note) : When using those keys, make sure the calculator is set for the
angle unit you want.
