How to prove a function is equicontinuous?Continuous Functions:The functions that are free of holes or breakpoints are known as continuous functions. The equicontinuous functions are a special category of continuous functions. The equicontinuous functions generally exist in the compact metric spaces....
How to prove a function is periodic? Given: y' = 2xy, y(1) = 1 Find y(1.2) using the Runge-Kutta method with a step size of h=0.2. Let f: Z_12 → Z_12: x → 9 x + 1 where arithmetic is done modulo 12. a) Show that f is neither injective, nor surjective. b) Now ...
In mathematics, two sets or classes A and B are equinumerous if there exists aone-to-one correspondence(or bijection) between them, that is, if there exists a function from A to B such that for every element y of B, there is exactly one element x of A with f(x) = y. Is QA co...
statement of the form A implies B to prove, their method of proof is generally wholly inadequate. He jokingly said, the student assumes A, works with that for a bit, uses the fact that B is true and so concludes that A is true. How can it ...

How to prove a function is a bijection? How do I show that {1, 2, 3, 4, . . . } has the same cardinality as {. . . , -4, -3, -2, -1, 0, 1, 2, 3, 4, . . . }? How to prove a set is compact? Show that: If A is any set, then there is no surjection of...
How to prove that a function exists?Function in Math:The function can exist or can't exist, that depends on if the function is function or a relation. So we have to test the function if it is not a relation, in order to guarantee its nature and type....

How to prove a function is surjective? How to prove that a set is dense? Does this use Rolle's theorem? How would one prove this? How to prove a set is open? Prove that the number of edges in a bipartite graph with n vertices is at most \frac{n^2}{4}. Given: \overline{JK}...
Let Φ: R → S be a surjective homomorphism from the ring R to the ring S. Prove that if T is a subring of R, then the set W = {b ∈ S such that b = Φ(c) for some c ∈ T} is a subring of S. How to prove a set is a ring?
