I lent it to someone approximately 35 years ago and never got it back. It is not one of the texts by Thomas, Spivak, Kline or other well known authors of beginning calculus books. Some day I am going to find it again, but unfortunately great books especially on subjects that most of the public are not especially interested in do not always become popular. I will make another attempt and if I find it, I will let you know the title and author.
Thank you very much!
I am also very interested in finding out about this book!
Please let me know too
