📚  The CoCalc Library - books, templates and other resources

solve 3n+1 Problem. `h(x)=4*x+1` and `v(x)=(2*x-1)/3 or (4*x-1)/3` iterate to Collatz-Odd-Tree

PythonTeX example: have LaTex \maketitle show local date instead of UTC date.

All published worksheets from http://sagenb.org

This notebook counts and displays the number of permutations that avoid any two patterns

My random explorations into number theory and various statistics and distributions of arithmetic functions. These are my rambles and should not be taken as any more than that. I do hope to have lots of cool graphs and plots. I also will include failed ideas, since I think it's important to show those as well. Will be frequently updated.
