comment Is there a text that provides the proof of Fermat's Last Theorem?
Wiles' proof was actually in June 1993; an erratum was seen in the September of that year. Wiles went away and published his full account of the Taniyama-Shimura Conjecture (or the Modularity Theorem) in September 1994.

comment Prove $(1+ \tan{A}\tan{2A})\sin{2A} = \tan{2A}$.
@user36790 I agree with you, from what I saw I couldn't see how it was a hint but that could be my failure. Anyway you've netted to zero with me! All the best.

comment Calculating better value products.
Consider price per gram. For promotion tins this is $80/300=0.27$c per g. For the large tin this is $112/500=0.22$c per gram. Since $0.22 \leq 0.27$ the large tin is better value.

@user36790 I downvoted due to a terrible first attempt at an answer. Since your edit you've made it the best on offer IMO and I have upvtoted you again. Shame I can't give a +2! Cheers.
