2. Function Calculations
• Press
to set to the common function calculation mode. Press
¬
to clear
display.
• Check to make sure that the SET UP settings are as shown on CHAPTER 1 “10.SET
UP Menu” on page 20.
• There are two groups of functions. The functions of one group are directly accessible
from keys (such as log, sin, cos, etc.). The functions of the other group are selected
from menu screens (such as 2
x
, sinh and
∫
in the MATH, CALC menu.)
• Functions that are directly accessible from keys:
Trigonometric functions (sin, cos, tan)
Inverse trigonometric functions (sin

, cos
-1
, tan

)
Square (
