2 Mean Value Theorems 51 Proof Since f is delta differentiable at each point of [a, b], f is continuous on [a, b]. Therefore, there exist ξ1 , ξ2 ∈ [a, b] such that m = min f (t) = f (ξ1 ) and M = max f (t) = f (ξ2 ). t∈[a,b] t∈[a,b] Because f (a) = f (b), we assume that ξ1 , ξ2 ∈ [a, b). 1. If σ (ξ1 ) > ξ1 , then f Δ (ξ1 ) = f (σ (ξ1 )) − f (ξ1 ) ≥ 0. σ (ξ1 ) − ξ1 2. If σ (ξ1 ) = ξ1 , then f Δ (ξ1 ) = lim t→ξ1 f (t) − f (ξ1 ) ≥ 0. t − ξ1 3. If σ (ξ2 ) > ξ2 , then f Δ (ξ2 ) = f (σ (ξ2 )) − f (ξ2 ) ≤ 0.
Therefore, every point of T is right-scattered. We note that the function f is continuous in T. 14 Let T = for t ∈ Tκ . Solution 1 + 5 4 (t 4 + 2)3 + t 2 t 4 + 2 + t t 4 + 2 + t 3 . 4 √ 5 n + 1 : n ∈ N0 and f (t) = t + t 3 for t ∈ T. Find f Δ (t) √ 5 (t 5 + 1)2 + t t 5 + 1 + t 2 . 15 Let T = Z and f be differentiable at t. Note that all points of t are right-scattered and σ (t) = t + 1. Therefore, f Δ (t) = = f (σ (t)) − f (t) σ (t) − t f (t + 1) − f (t) t +1−t = f (t + 1) − f (t) = Δf (t), where Δ is the usual forward difference operator.
Solution f is increasing for t ∈ (−∞, −1] ∪ [3, ∞) and f is decreasing for t ∈ [0, 2]. 52 (Chain Rule) Assume g : R → R is continuous, g : T → R is delta differentiable on Tκ , and f : R → R is continuously differentiable. 5) ( f ◦ g)Δ (t) = f (g(c))g Δ (t). Proof Fix t ∈ Tκ . 3 Chain Rules 57 1. If t is right-scattered, then ( f ◦ g)Δ (t) = f (g(σ (t))) − f (g(t)) . 5) holds for any c ∈ [t, σ (t)]. Assume that g(σ (t)) = g(t). Then, by the mean value theorem, ( f ◦ g)Δ (t) = f (g(σ (t))) − f (g(t)) g(σ (t)) − g(t) g(σ (t)) − g(t) μ(t) = f (ξ )g Δ (t), where ξ is between g(t) and g(σ (t)).
