Occasionally, out-of-print instructor supplements appear here. Look for "Instructor's Manual" alongside the .zip keyword.
Before diving into the solution manual, let’s contextualize the textbook.
The book is famous for its terse solutions and "starred" problems that often require deep insight.
Given the legal ambiguity, here are safer alternatives that contain the same or superior content: The book is famous for its terse solutions
Some professors publish their solutions for enrolled students. Search:
"Differential Geometry" "Do Carmo" solutions site:.edu
This is the gray area. Do Carmo’s book is under copyright. While the problems themselves are not copyrightable (facts and mathematical statements), the expression of their solutions may be. Many universities have policies against sharing full solution manuals for current textbooks.
That said, a significant portion of these .zip files circulate under "fair use for educational purposes." However: The file is almost never an official release
Warning: Avoid sites asking for credit card or survey completion—these are scams. A free .zip file for Do Carmo should not require payment.
When you search for "do carmo differential geometry of curves and surfaces solution manual.zip", you are looking for a compressed folder containing unofficial solutions. Typically, the file structure looks like this:
do_carmo_solutions.zip
│ README.txt
└───Chapter1/
│ │ sec1_curves.pdf
│ │ sec2_arc_length.pdf
│ │ sec3_Frenet.pdf
└───Chapter2/
│ │ regular_surfaces.pdf
└───Chapter3/
│ │ first_fundamental_form.pdf
└───Chapter4/
│ │ gauss_map.pdf
└───Chapter5/
│ │ geodesics.pdf
└───Appendix/
│ point_set_topology.pdf
The file is almost never an official release from Do Carmo or his estate. Instead, it is a community-aggregated set of handwritten or typed solutions, often compiled from: Some versions are clean LaTeX documents
Some versions are clean LaTeX documents; others are scanned notebooks with coffee stains.
The .zip file you mentioned is not an official, authorized release. do Carmo's publisher (Prentice-Hall, now Pearson) has never published an official solutions manual for this book. Any circulating .zip file is:
