2-4 Function Calculations
Now perform calculations by using functions. Frequently used functions can be
input at one touch
of the respective function keys.
• Trigonometric Functions (sin, cos, tan) and Inverse Trigonometric Functions
(sin-
1
,
cos-
1
,
tan-
1
)
When using these functions, be sure to specify the angle unit (degrees, radians,
grads).
Example:
sin 12.3456° = 0.2138079201
