Cos (Source)
Returns the cosine of an angle specified in radians.
Syntax
x = Cos (source)
Remarks
Source can be any valid numeric expression measured in radians.
The Cos function takes an angle and returns the ratio of two sides of a right
triangle. The ratio is the length of the side adjacent to the angle divided by the
length of the hypotenuse. The result lies in the range -1 to 1.
To convert degrees to radians, multiply degrees by π/180. To convert radians
to degrees, multiply radians by 180/π.
Cos FunctionExample
The example uses Cos to calculate the cosine of an angle with a user-specified
number of degrees.
Dim Degrees, Pi, Radians, Ans 'Declare variables.
BeginProg
Pi = 4 * Atn(1) 'Calculate Pi.
Degrees = Volts(1) 'Get value to convert.
Radians = Degrees * (Pi / 180) 'Convert to radians.
Ans = Cos(Radians) ‘The Cosine of Degrees.
EndProg
CosH (Source)
The COSH function returns the hyperbolic cosine of an expression or value.
Syntax
x = COSH (source)
Remarks
The COSH function takes a value and returns the hyperbolic cosine [COSH(x)
= 0.5(ex + e-x)] for that value.
COSH Function Example
The example uses COSH to calculate the hyperbolic cosine of a voltage input
and store the result in the Ans variable.
