Grokking Modern System Design Interview for Engineers & Managers
Ace your System Design Interview and take your career to the next level. Learn to handle the design of applications like Netflix, Quora, Facebook, Uber, and many more in a 45-min interview. Learn the RESHADED framework for architecting web-scale applications by determining requirements, constraints, and assumptions before diving into a step-by-step design process.
In JavaScript, Math
is a built-in object that contains different methods and properties used to perform mathematical operations. It contains a cos()
function, which is used to compute the cosine of a specified angle.
Math.cos(param);
param
: This is the angle for which we want to compute the cosine. Its type is Number
, and it is measured in radians.
Number
in JavaScript is a 64-bit double-precision value which is the same asdouble
in C# or Java.
Number
: It returns the cosine of the given angle stored in param
. It is of the Number
type. Its range is:
NaN
: The function returns NaN
if param
is positive or negative Infinity
.
Use the following formula to convert degrees to radians:
- Radians = Degrees x
π
/180where
π
= 3.14159, approximately.
console.log("cos(-1) = " + Math.cos(-1));console.log("cos(0) = " + Math.cos(0));console.log("cos(1) = " + Math.cos(1));console.log("cos(∞) = " + Math.cos(Infinity));console.log("cos(-∞) = " + Math.cos(-Infinity));
