I had searched on the internet and I could not find the method of the Math object that returns the ctg and arcctg of an angle. Is there such a method or should I just create my own function using these mathematical formulas:

    you may have a look into the docs for [`Math`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math) (some methods may not be working on IE) – Nina Scholz Aug 31 '16 at 08:25
  • You should create your own functions. – Ivan Z Jan 27 '19 at 16:32

There is not, and if you want them you will have to define them yourself. Fortunately, they are easy:

function ctg(x) { return 1 / Math.tan(x); }
function arcctg(x) { return Math.PI / 2 - Math.atan(x); }
