1) For a forward difference table the points $$(x_0,y_0),(x_1,y_1),(x_2,y_2),dots$$ with $$h=x_1-x_0=x_2-x_1=dots$$ so on, and for the function $$y=x^n,$$ say, which of the following statements is true? A) $$frac{Delta^2y_0}{h^2}=12$$ B) $$frac{dy}{dx}=3x^2$$ C) $$frac{d^2y}{dx^2}=6x|_2=12$$ D) $$frac{Delta^2y_0}{h^2}=frac{d^2y}{dx^2}|_{x=x_1}$$   2) “If $$f(x)$$ is continuous in $$(a,b),$$ then for any $$x$$ in that interval, we shall...

[In Historical Perspective]      [Creators of Modern Topology] There are indications that there is growing interest among mathematicians in the history of the development of Mathematics. We believe that the there is reason to be glad with such a tendency. After many hundred years of explosive development,...
