Show that if x=lim a_n for some sequence (a_n) contained in A satisfying a_n not = x,then x is a limit point of A.
Let phi is a homomorphism from Z30 onto a group order 3. Determine the kernel of phi. Find all generators of the kernel of phi.
Let g:A->R and assume that f is a bounded function on A subset or equal to R (i.e there exist M>0 satisfying Absolute value of f(x)<=M for all x belong to A).
Show that if a function is continuous on all of R and equal to 0 at every rational point then it must be identically 0 on all of R.
How many ads of each type should be place to maximize the total number of people reached?
Problems in Galois Theory.Let K be a field of characteristic p > 0, and let c in K. Show that if alpha is a root of f (x) = x^p - x - c, so is alpha + 1. Pr
Consider the homomorphism Z[x]?Z that sends x->1. Explain what the correspondence theorem when applied to this map says about ideals of Z[x]
Prove that f must have a fixed point; that is, show f(x)=x for at least one value of x belong to [0,1].

A function is increasing on A if f(x)<=f(y) for all x
Prove that if f:A->R and a limit point c of A , lim f(x)=L as x->c if and only if lim f(x)=L as x->c^-(left handed limit) and lim f(x)=L as x->c^+(right handed
If lim f(x) as x->c does not exists for some other reason the discontinuity at c is called essential discontinuity.
Let g:[0,1]->R be twice-differentiable (i.e both g and g' are differentiable functions) with g''(x)>0 for all x belong to [0,1].if g(0)>0 and g(1)=1.

By an n-fold line subdivision of the plane P, we mean any collection of n-distinct (infinite) lines in P, together with the open regions in P.
If |z|>R, the terms of the series are unbounded and the series is consequently divergent.
