Sorry I haven't been posting much recently. I've been busy compiling a set of my top 10 best problems (the 3rd is based off of one of Sualeh Asif's) posts.and now I'm going to release them all at once as a set. There are some mechanics, calculus, Algebra, Geometry, NT, and combinatorics problems.
Most of these problems are very challenging (lvl 4-5) but all of them have very elegant solutions. Please, if you like a problem, kindly like and reshare it because I worked very very hard on all of these.
Btw, incase you're wondering why it's my top 10 and not 11 it's because one problem here isn't exactly original since I made one similar before.
Numbers next to links represent relative difficulty in this set. Not the actual level of the problem
FOR THOSE WHO WANT A CHALLENGE, Try the problems with ** next to them
**Angle Trisector(this is my favorite) 5
Triangle Area Sum(based off of a problem I made before that didn't get too popular, but I'm reposting it cuz I feel it's is a good problem) 4
The Greatest Sin 3.5-4
**Rotating a Graph 4.5
