Returns the cosine of the number.
Cos ( X )
Numeric value
//The value of variable x is the value of the cosinus
//of the current value of the database
//field {Angles} for each evaluation of this formula
NumberVar x = Cos({Angles})
//some special values of sinus Cos(0) //1 Cos(0.5*pi) //0 Cos(pi) //-1 Cos(1.5*pi) //0 Cos(2*pi) //1
