COS
Function
COS
• Returns a cosine value of the trigonometric function
COS ( <arithmetic expression> )
Syntax
arithmetic expression
• • • •
Specify a numeric value in radian.
Examples
A=COS(3.14159/180 60)
• • • •
Converts 60° angle to radian, calculates its cosine
value, and stores in A.
Description
• The COS function returns a cosine when the <arithmetic expression> value is given in
radian ((
π
/180) x angle).
• <arithmetic expression> can be any numeric value type, but the COS function always
calculates in single precision.
Program Example
10 ' Calculates cos 60°C
20 A=(3.141592653#*60)/180
:
' Converts 60°C to radian
30 B=COS(A)
:
' Calculates cos
40 PRINT "60°C =";A;"radian"
50 PRINT "cos 60°C =";B
RUN
60°C
= 1.0472 radian
cos 60°C
= .5
