The Cos function returns the cosine of a specified number (angle).
Its parameter is number, which describes a numeric expression that
expresses an angle in radians. The number argument can be any
valid numeric expression that expresses an angle 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 pi /180.
To convert radians to degrees, multiply radians by 180/pi.
The following example uses the Cos function to return the cosine
of an angle :-
| Dim MyAngle, MySecantMyAngle
= 1.3 ' Define angle in radians.MySecant = 1 / Cos (MyAngle)
' Calculate secant. |
The Syntax of the Cos function is :-
Example#1 :-
Code :-
document.write(Cos(50.0))
Output :-
0.964966028492113 |
Example#2 :-
Code :-
document.write(Cos(-50.0))
Output :-
0.964966028492113 |
Example#3 :-
Code :-
<% =Cos(45.0) %>
Output :-
0.52532198881773 |
Note :- You can also use a negative number (angle).
Example#4 :-
|
Code :-
<% =Cos(-45.0) %>
Output :-
0.52532198881773
