  This manuscript, titled Differential Geometry of Curves and Surfaces in
Three-dimensional Euclidean Space, is intended for undergraduate students of
mathematics and other sciences with the need of use of Euclidean differential
geometry. We deal with the differential geometry of curves and surfaces in
three dimensions, covering all the main definitions, ideas and concepts needed
for successful understanding and further application of this fundamental branch
of mathematics. Many concrete examples with solutions are given with
illustrations.

  Ova knjiga namijenjena je dodiplomskim studentima matematike i drugih nauka
sa potrebom upotrebe euklidske diferencijalne geometrije. Upoznat \'cemo se sa
diferencijalnom geometrijom krivih i povr\v{s}i u tri dimenzije, pokrivaju\'ci
sve glavne definicije, ideje i koncepte potrebne za razumijevanje i
uspje\v{s}nu dalju primjenu ove fundamentalne grane matematike. Dati su mnogi
konkretni problemi sa rje\v{s}enjima i mno\v{s}tvom ilustracija.
