Why hypot() function is so slow?
I did some testing with C++ hypot() and Java Math.hypot. They both seem to be significantly slower than sqrt(a*a + b*b). Is that because of a better precision? What method to calculate a hypotenuse hypot function uses? Surprisingly I couldn't find…

How to print the pythagorean triple with the largest hypotenuse
I have to find all the pythagorean triples which have a value of "c" (where c is the hypotenuse) smaller than an integer number entered by the user. I was able to do this, however I also have to print which triple has the largest value of "c".

The Math.hypo function
Why the math operation Math.sqrt(x*x+y*y) is much faster than Math.hypo(x,y)?

How can I find the arctan of a right triangle using only the hypotenuse?
Okay, so I need to make C go the shortest path from A to B. A to B is the hypotenuse of my right triangle, and I need to give C the arctan of said triangle. How do I do this, and does the formula have a name?

2d random walk in python - drawing hypotenuse from distribution
I'm writing a simple 2d brownian motion simulator in Python. It's obviously easy to draw values for x displacement and y displacement from a distribution, but I have to set it up so that the 2d displacement (ie hypotenuse) is drawn from a…
