I am an engineer who is in love with math and lifelong math student. I love to learn new things in mathematics for self-satisfaction. My idols are Gauss , Euler , Ramanujan because they were in love with math as I feel.

comment To find the volume of the region that is bordered by 4 points in 3D space
I tested the formula on a simple 4 points examples such as $(0,0,0),(1,0,0),(0,1,0),(0,0,1)$ that $V=1/6$.It should be factorial factor as you said for $3D$. I missed that point but I wonder how to prove that it is true for higher dimensions. We cannot figure out in mind the higher dimensions than 3D,can we? How did they prove that? Do you know a related links or reference books for that subject? Thanks a lot for your help.

comment To find a fifth degree equation by using circles and lines that cannot be solved by radicals
@mercio : I am aware that circles and lines is solvable by square roots, I wonder if we try to find angles (trigonometric equations. Please see my previous question). Thanks
