About 40 years ago, I had a "Handbook of Mathematical Equations". It was hardcover with an orange dust jacket. I seem to have lost it and I may not even be remembering the exact name. Does anybody recognize the book by my description and know if it is available, in-print or out-of-print?
Alternatively, can someone recommend a comprehensive handbook of math?

how about this one from the 1960s: https://www.amazon.com/Mathematical-Handbook-Scientists-Engineers-Definitions/dp/0486411478
You're probably thinking of Handbook of Mathematical Functions, Milton Abramowitz and Irene A. Stegun, Eds., National Bureau of Standards Applied Mathematics Series, Vol. 55, published by the U.S. Department of Commerce, 1964, 1046pp. This hardback edition has an orange cover.
There's also a Dover edition that was printed in paperback.
