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).
