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:
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); }
