I've been messing with this proof for while and I'm stuck on this. I've started with a(n) converges to 0, let epsilon > 0, then there exists an n0 in N such that for all n >= n0.

I'm stuck here thus far. Any help? Thanks for your time.

The rest of your thought is
For all n >= n0, ##\sqrt{a_n} < \epsilon##.

What are the given conditions? Is it an converges to 0? You have an = 0 in the title.

Yes it converges to zero
 
Can you prove that sqrt(an) is eventually less than 1/100 ?

How about that sqrt(an) is eventually less than 1/(1000000) ?
 
A sphere as topological manifold can be defined by gluing together the boundary of two disk. Basically one starts assigning each disk the subspace topology from ##\mathbb R^2## and then taking the quotient topology obtained by gluing their boundaries. Starting from the above definition of 2-sphere as topological manifold, shows that it is homeomorphic to the "embedded" sphere understood as subset of ##\mathbb R^3## in the subspace topology.
