1. Would it be possible if you helped me on a thread in the Trigonometry Forum? I am still stumped.
2. Thanks so much evinda!
3. Thanks evinda , sorry for late reply. I am busy with exams these days.
4. Thank you very much, evinda!
5. Hey evinda,

I think if you ask for the proof of FLT for n = 4 in a different thread it would be better as it would be off-topic on the current thread. If you post it as a separate question, I'd be more than willing to answer to it.
6. Thank you very much!!!
7. Thanks, but I would have liked to stay 13.
8. Ok,thanks!!!!
9. Hello and welcome to MHB, evinda!

If you have any questions or comments about the forums, please feel free to address them to me or another staff member. We are happy to help, and look forward to your participation here!

Best Regards,

Mark.
