The double angle formula calculator can be used to find the double angle value of any of sin , cos and tan . Let us consider an example. Suppose we wish to find the values of the sin 120o, cos 120oand tan 120o. How would we do that?
The double angle formula finds the value of a trigonometric function of twice an angle. Read the proof of the double angle formula and see it in...

Double the cosine of the argument. Attributes RegisterAttribute Remarks Returns the trigonometric cosine of an angle. Special cases: If the argument is NaN or an infinity, then the result is NaN. If the argument is zero, then the result is1.0. Java documentation forjava...
Cos(a - b) is one of the important trigonometric identities used in trigonometry to find the value of the cosine trigonometric function for the difference of angles. Learn the cos(a-b) formula using solved examples.
The COS function is a built-in function in Excel that is categorized as aMath/Trig Function. It can be used as a worksheet function (WS) and a VBA function (VBA) in Excel. As a worksheet function, the COS function can be entered as part of a formula in a cell of a worksheet. As...
()/180. It can be used as a worksheet function (WS) and VBA function, and Microsoft Excel. If we are using it in the worksheet function, we can enter the formula in a cell of a worksheet, and if we are using it through VBA, it should be entered as macro code in Microsoft ...
Function Cos2(angle As Double) As Double 'using the "Round" function to round up the output to 2 decimal places tCos2 = Round(Cos(angle), 2) End Function Now, we can use this function just like any other Excel formula. We can pass an angle in radians or use the “Radians” funct...
