Javascript math cos() is an inbuilt function that is used to find the cosine value of the given number. Since **cos()** is a static method of **Math**, it can be used without creating an object. The **Math**.**cos()** function in **Javascript** is used to return the **cosine** of that number. Javascript **cos()** method returns the numeric value between -1 and 1, which represents the **cosine** of an angle given in radians.

To find the cosine value of a given argument in JavaScript, the **Math.cos()** method is used. This method comes handy in programming contexts dealing with any trigonometric expressions.

`Math.cos(x)`

The variable x (in radians) whose cosine value is to be determined.

What are the differences? Do they each have specific use contexts?

In this article we will discuss full details and comparison of both Ember.js and Vue.js

In this article, we will have a look at the call(), apply() and bind() methods of JavaScript. Basically these 3 methods are used to control the invocation of the function.

Vue.js is an extensively popular JavaScript framework with which you can create powerful as well as interactive interfaces. Vue.js is the best framework when it comes to building a single web and mobile apps.
