All functions can be plotted as angle slopes rather than rise/run with range in interval (-π/2, π/2).

All functions can be plotted so that their range is (-π/2, π/2) or is contained in (-π/2, π/2).

In this video, I show you that a derivative is just like any other function, with the exception that the plot is not done in terms of rise/run but rather in terms of angle so that for a curve that is smooth over a given interval, there is a derivative at every point.

It's a crime that garbage channels such as Numberphile, One red-one brown, etc have such a high subscriber couunt and yet all you get is absolute rot from mainstream morons who don't know shit about mathematics or calculus.

Be sure to study my geometric theorem which allows for a rigorous formulation of the bullshit mainstream calculus in terms of sound geometry:

I am the greatest mathematician today. I am a genius and I do know better than anyone else. Don't believe me - investigate my claims.
