Arithmetic is the technology of acts with out issues - and during this, of items you could outline by means of acts. 1 Paul Valéry The essays gathered during this quantity shape a mosaik of thought, learn, and perform directed on the job of spreading mathematical wisdom. They tackle questions raised by way of the recurrent remark that, all too usually, the current methods and technique of educating arithmetic generate within the scholar a long-lasting aversion opposed to numbers, instead of an figuring out of the important and infrequently mesmerizing issues you'll be able to do with them.

6 may be slightly varied to give useful results. 4 may be revised as follows: suppose that f ∈ R[a, b] and that there is a continuous function F : [a, b] → R such that F is differentiable b on (a, b) and F ′ (t) = f (t) for all t ∈ (a, b). Then a f = F(b) − F(a). 4. 6 may be similarly revised. 4 is a natural question of existence: which functions in R[a, b] have a primitive? The second fundamental theorem of calculus, given below, provides a partial result in this connection. 4 show that f ∈ R[a, b] has a primitive if, and only if, x the mapping x −→ a f is differentiable and has derivative f .

Define F : J → R by ⎧ x ⎪ if x > a, x ∈ J, ⎨ a f F(x) = 0 if x = a, ⎪ ⎩ a − x f if x < a, x ∈ J. Then F is continuous. If f is right- (left-) continuous at x0 ∈ J , then F is right(left-) differentiable at x0 and ′ ′ F+ (x0 ) = f (x0 ) (F− (x0 ) = f (x0 )). 4 Evaluation of Integrals: Integration and Differentiation 25 In particular, if f is continuous at x0 , then F is differentiable at x 0 and F ′ (x0 ) = f (x0 ). Proof Suppose that b ∈ J , b > a. Then f ∈ R[a, b] and there exists a real number M, depending on b, such that | f (t)| < M if a ≤ t ≤ b.

4) if α = −1. c Since limv→∞ c f exists in R if, and only if, α < −1; and limu→0+ u f exists in R if, and only if, α > −1, (iii) follows immediately. 7. 9 Let a, b ∈ R, a < b; let f : (a, b) → R be bounded and in Rloc (a, b); suppose that g : [a, b] → R is such that g |(a,b) = f . Then g ∈ R[a, b], f is improperly Riemann-integrable over (a, b) and b (I R) a b f = g. 8, g ∈ R[a, b]. 5. 10 Let f : (0, 1) → R be given by f (x) = (log x) log(1 − x) for 0 < x < 1. We claim that f is improperly Riemann-integrable over (0, 1).
