This math coach is really cool, but only in Penrith. He made thousands of tricky ways to finish problems, fast and fast, and easily. Anyone knows someone having some styles like that?

I wouldn't consider "many tricky ways" to solve problems effective. What you want is to learn the basic concepts so that you know how to think them out rather than relying on "tricks". In this particular example, he is just showing how to use the "formula" that $\displaystyle \frac{d x^n}{dx}= nx^n$. If he has shown, previous to this, how to get that formula, that would be better to show.

There's a Youtuber called Blackpenredpen who does tricky integration problems and other calculuslevel problems in a very clear and entertaining way. He gets his name from the fact that he holds two markers in his hand and effortlessly switches between them to make his symbology more clear. I wish I'd had a teacher like this for calculus.

Yes. I think no longer, people will get on with the trend of teaching students by making them impressed more than force them to do.

Perhaps you meant Penrith. Perth's on the other side of Australia.
