Would you please answer this question for me? Thank you in advance I want to have a very respectful letter to send to a professor. What is your opinion about the following message? Is it polite? or does it need to change in some parts? Dear Professor ....... Around two months ago, I have communicated with you for over 10 days and during that time and through your guidance, I could correct xxxxx equation which had been miscalculated by myself earlier. Now I have written a paper and I want to submit it. xxxxx equation is used as some part of basic calculation in the paper. In the section acknowledgement, if you accept, I want to appreciate you for your advice but before that I'd like to inform you about this task. Please tell me whether you agree or not. Best regard the formal name will be replaced here
