Theory of Maxima and Minima 



By HARRIS HANCOCK 



University of Cincinnati 



Makes available in English the impor- 

 tant advances in this branch of mathe- 

 matics that have for some time been ac- 

 cepted in Europe but that have not 

 been accessible to our students in their 

 own language. It contains numerous 

 examples, problems, and exercises taken 

 from algebra, geometry, physics, me- 

 chanics, and other branches of mathe- 

 matics hitherto regarded as somewhat 

 foreign to the subject.
