pretend infinity border is 10 grid and derivative #4 Textbook 2nd ed. : TRUE CALCULUS; without the phony limit concept 
  Alright, in the next edition I need to use the 10 grid more than the 10^-603 grid so that High School students have an easy time with True Calculus. Now I have the four functions: y = 3 (type of a box function) y = x (identity function) y = x^2 y = 1/x (similar to a type of a logarithm function)... more »

Finding paths in trees from Random Forests 
  If you have a set of trees that are produced over a subset of features (Random Forest application in Machine Learning)in order to average their results and classify some x, what techniques could you use to record the paths taken by the trees to understand the decision that was made? Or if that isn't really feasible, what could help you gain insight into what contributed to the classification of some x based on all your trees in your random forest?... more »

Cartesian Coordinate System, the union of geometry with numbers #0 Textbook 2nd ed. : TRUE CALCULUS; without the phony limit concept 
  The beauty of future editions of a textbook is that errors can be removed and improvement of teaching can be improved. Already I made a major error, in that suggesting that we do not connect points of the graph of the function when we have holes between points, for we certainly do connect them since the hypotenuse atop the picketfence is... more »

Does this imply that lim x --> oo f'(x) = 0? 
  Suppose f:[0, oo) --> R is increasing, differentiable and has a finite limit as x --> oo. Then, must we have lim x --> oo f'(x) = 0? I guess not, but couldn't find a counter example. Thank you

the derivative #3 Textbook 2nd ed. : TRUE CALCULUS; without the phony limit concept 
  the derivative #3 Textbook 2nd ed. : TRUE CALCULUS; without the phony limit concept Alright, I will work with these four functions as listed previously: y = 3 y = x y = x^2 y = 1/x The key geometry model for both the derivative and the integral is the Picket-fence model. It is a slender thin rectangle which atop sits a... more »
