The Excel COS function returns the cosine of an angle given in radians. To supply an angle to COS in degrees, use the RADIANS function to convert to radians. Purpose. Get the cosine of an angle provided in radians. Return value. The cosine value. Syntax. = COS (number) number - The angle in radians for which you want the cosine. How to use.
Some of them are cot x = 1/tanx , six x/cos x = tan x, sin(900-x) - cos x and so on. Excel offers a number of built-in functions that deal with trigonometry. You can use these trig functions to solve complex trigonometric expressions.

Key Takeaways. The COS Excel function is a built-in Math & Trig function used to find the cosine value of a given angle. Mathematically, we can use Cos Ɵ = Adjacent side/hypotenuse in a right-angled triangle and the COS function in many practical applications such as finding heights, calculating phase angles in electrical circuits, and so on.
The COS function in Excel calculates the cosine of an angle specified in radians and returns the corresponding value. The COSH function returns the value of the hyperbolic cosine of the given real number.
Excel uses several built-in trig functions. Those that you will use most often are displayed in the table below. Note that the arguements for the SIN ( ), COS ( ) and TAN ( ) functions are, by default, radians. Also, the functions ASIN ( ), ACOS ( ) and ATAN ( ) return values in terms of radians.
