- Prove the conjecture made in the previous exercise.arrow_forwardLet R be the set of all infinite sequences of real numbers, with the operations u+v=(u1,u2,u3,......)+(v1,v2,v3,......)=(u1+v1,u2+v2,u3+v3,.....) and cu=c(u1,u2,u3,......)=(cu1,cu2,cu3,......). Determine whether R is a vector space. If it is, verify each vector space axiom; if it is not, state all vector space axioms that fail.arrow_forwardLet f(x),g(x),h(x)F[x] where f(x) and g(x) are relatively prime. If h(x)f(x), prove that h(x) and g(x) are relatively prime.arrow_forward
- 4. Let , where is nonempty. Prove that a has left inverse if and only if for every subset of .arrow_forwardFor an element x of an ordered integral domain D, the absolute value | x | is defined by | x |={ xifx0xif0x Prove that | x |=| x | for all xD. Prove that | x |x| x | for all xD. Prove that | xy |=| x || y | for all x,yD. Prove that | x+y || x |+| y | for all x,yD. Prove that | | x || y | || xy | for all x,yD.arrow_forwardFind all monic irreducible polynomials of degree 2 over Z3.arrow_forward
- Let X N (10, 23). Then P( X < 10) =arrow_forwardLet f be a continuous, increasing function on [a, b] and let P be a partition b-a for all i = 1, 2, ..., n. Show that Problem 1. of [a, b] into n equal intervals, i.e. A¤i n a Uf(P) – L;(P) = (F(b) – f(a)): | narrow_forward- Let X~N(10,9). Find P(1 < X < 10).arrow_forward
- If fn is a uniformly equicontinuous sequence of functions on a compact interval and fn → ƒ pointwise, prove that fn → f uni- formly. (You should not assume that f is continuous, although this is a consequence of the result.)arrow_forwardA continuous function f [0, 1] → R satisfies f(0) = f(1). Show that for : each integer n ≥ 1 there exits x such that f(x+(1/n)) = f(x). Is the same statement true for numbers other than 1/n?arrow_forwardA sequence {ann21 contained in the interval [0, 1] is uniformly distributede if and only if lim — [ f(a) = f f(x) dx nào n k=1 -holds for any continuous function f(x) defined on [0, 1].arrow_forward
