Configuration
ATN(argument)
The argument can be a numeric expression or numeric constant
in radians. The value returned will be the primary angle
TT TT

< angle < 2)
Example
10 Pl= ATN(1) * 4
20 PRINT Pl, ATN(TAN(.2))
]RUN [Ret]
3.14159266 .2
In
the preceding example, the arctangent of 1 returns the value
TTl4. Multiplying this value by 4 returns the value indicated.
In the second part of the PRINT statement, the argument .2 is
returned. Since the ATN formula is the inverse of the TAN
function, the value returned was the original argument.
AUTO

The AUTO command generates a new line number every time
the user presses Return .
Configuration
AUTO line number [,increment]
Both linenumber and increment must be integers. The /ine-
