## Cosine Calculator | Cos(x)

Using this cosine calculator, you can simply calculate the cosine value of given angle theta. Cosine of angle is one among the three trigonometric ratios. The cosine of an angle ‘α‘ is defined as the ratio between the adjacent side ‘b’ and the hypotenuse ‘c‘. cos (α)= adjacent/ hypotenuse = b/c Calculator Use This calculator … Read more
