Cosine also known as cos is one of the basic trigonometric functions. These trigonometric functions can be learnt with the right angled triangle. The cosine can be defined as the ratio of the adjacent angle to the hypotenuse angle. It can also be defined as the sine of the complementary or co-angle. This cosine or cos x calculator helps to calculate cos of an angle. Enter the input angle and the cosine calculator will provide you the cos of the given angle in radians and degrees.
