Any plans for provincial combined mathematics teacher training program for southern province planned?
We already had the program in the current series in the Southern Province. It was held in 2022. Did you miss it?

The usefulness of conservation laws lies in their application over a period of time. If you are applying it for a collision, you will be applying it to get information on the velocities just before and just after the moment of impact.
Therefore, the more appropriate way to get that information is to apply I=Δ(mv) since it is the equation governing the sudden change in momentum.

Well-written response Bourbaki! In addition, to answer Dilshanwj's question, when factors of x^2 -36 are considered (x-6) and (x+6) are the only irreducible factors of it over R (real numbers). By a factor of a polynomial, we mean, a 'polynomial' that divides the given polynomial. Any factorizationRead more

In addition, to answer Dilshanwj’s question, when factors of x^2 -36 are considered (x-6) and (x+6) are the only irreducible factors of it over R (real numbers). By a factor of a polynomial, we mean, a ‘polynomial‘ that divides the given polynomial. Any factorization that you have suggested leads to non-polynomial expressions.

The response given by Bourbaki aptly describes why we don't consider 1 as a Prime.

We have plenty of applications related to convergent geometric series but not for this particular case. I believe the method used here can be totally new approach. The most important thing here is I’m using only one figure and basic geometry theorems. All points named in the figure have integer coordinates but because of practical difficulties I couldn’t draw a perfect figure in GeoGebra. Here you have the link for more details,
