# Cosine

In this cosine category you can find our posts discussing a particular value of the aforementioned trigonometric function for both, the unit radian as well as for degrees. Besides the result for a specific angle or x, we also provide you with identities and the derivative, along with the geometric significance. In every article, e.g. cos 0.5, we also give you directions for further information, and then shed a light on the specific frequently asked questions. However, at the bottom of each post you can fill in the comment form if something about the cosine function remains unclear or if you like to give us feedback. In addition, how you may use our search box is always explained – the method is also recommended for looking a value or entry in this category up. On top of all is our cosine calculator, which lets you choose whether you want the result in degrees or radians.
