take the cotangent of a number in javascript

To take the cotangent of a number in javascript, you can use the following function:

index.tsx
function cot(x) {
  return 1 / Math.tan(x);
}

Where x is the input angle in radians.

This function first computes the tangent of the input angle using the Math.tan method, and then returns the reciprocal of the result.

You can call this function with any angle in radians to get the cotangent of that angle. Here's an example:

index.tsx
const x = Math.PI / 4; // angle in radians
const cotX = cot(x); // cotangent of x
console.log(cotX); // prints 1

In this example, the input angle x is π/4 radians (which is equivalent to 45 degrees), and the cotangent of this angle is 1. The console.log statement prints the resulting cotangent to the console.
