NJ-series Instructions Reference Manual (W502)
SIN, COS, and TAN
These instructions perform trigonometric calculations on real numbers.
*1 If you omit an input parameter, the default value is not applied. A building error will occur.
*2 The valid range is −1.000000e+0 to 1.000000e+0 for REAL data. The valid range is
−1.00000000000000e+0 to 1.00000000000000e+0 for LREAL data.
SIN: Finds the sine of a number.
COS: Finds the cosine of a number.
TAN: Finds the tangent of a number.
