Chapter 4. Programming
COS (Cosine)
[Function] Stores the sine (SIN) of the data in Operand 2 in the variable in Operand 1. Stores the sine of the contents in the
variable in Operand 2 in the Operand 1 variable. If there is a post instruction (flag, output port), it turns ON
when the computation result is zero. (Be sure to input a real number variable 100~199 in Operand 1. This is the
same when placing a variable no. in Operand 2. The data in Operand 2 must be expressed in radians instead of
as an angle (degrees). A maximum of 7 digits can be input for the floating point.)
[Example] SIN 100 0.988031
SIN 0.988031 (radian) is 0.5, and after performing the command, variable 100 becomes 0.5.
SIN 100 *101
When the content of variable*101 in Operand 2 is 0.988031 (radian), then SIN 0.988031 (radian)
becomes 0.5, and after performing the command, variable 100 becomes 0.5.

[Function] Stores the cosine (COS) of the data in Operand 2 in the variable in Operand 1. Stores the cosine of the contents
in the variable in Operand 2 in the Operand 1 variable. If there is a post instruction (flag, output port), it turns
ON when the computation result is zero. (Be sure to input a real number variable 100~199 in Operand 1. This
is the same when placing a variable no. in Operand 2. The data in Operand 2 must be expressed in radians
instead of as an angle (degrees). A maximum of 7 digits can be input for the floating point.)
[Example] COS 100 1.047197
COS 1.047197 (radian) is 0.5, and after performing the command, variable 100 becomes 0.5.
COS 100 *101
When the content of variable*101 in Operand 2 is 1.047197 (radian), then COS 1.047197 (radian)
becomes 0.5, and after performing the command, variable 100 becomes 0.5.
