Let f: [0 1] → R be a function of the class c ^ 2 that
satisfies the differential equation f '' (x) = e^xf(x) for all x in
(0,1). Show that if x0 is in (0,1) then f can not have a positive
local maximum at x0 and can not have a negative local minimum at
x0. If f (0) = f (1) = 0, prove that f = 0
Let A ⊆ R, let f : A → R be a function, and let c be a limit
point of A. Suppose that a student copied down the following
definition of the limit of f at c: “we say that limx→c f(x) = L
provided that, for all ε > 0, there exists a δ ≥ 0 such that if
0 < |x − c| < δ and x ∈ A, then |f(x) − L| < ε”. What was...
