Numeric expression
Obtains the value of a trigonometric function for a given argument.
Parameter:
Argument-:
Explanation:
Numeric expression
- 1440° < I argument I< 1440° (degrees)
- 8
7r
< I argument I< 8
7r
(radians)
- 1600 < I argument I < 1600 (grads)
However, for TAN, " IArgument l = (2n - 1)
*
1 right
angle" is excluded.
1 right angle = 90° =
f
rad = 100 grad.
1) Obtains the value of a trigonometric function for a given argument.
2) The value depends on the angle unit setting; DEG, RAD or GRA (by the
~
key or MODE command).
3) As a rule, the argument is enclosed in parenthesis but the parenthesis can be
omitted if the argument is a variable or a numeric value.
