Ferrers.— AN elementary treatise on trilinear 



CO-ORDINATES, the Method of Reciprocal Polars, and the 

 Theory of Projectors. By the Rev, N. M. Ferrers, M. A., Fellow 

 and Tutor of Gonville and Caius College, Cambridge. Second 

 Edition. Crown 8vo. 6^-. 6d. 



The object of the author in zvriting on this subject has mainly been to 

 place it on a basis altogether independent of the ordinary Cartesian 

 system^ instead of regarding it as only a special foi'in of Abridged 

 Notation, A shoi-t chapter on Determinants has been introduced,

 Methods. By Percival Frost, M. A., late Fellow of St. John's 

 College, Mathematical Lecturer of King's College, Cambridge.

difficulties 



encountered by the student on first reading the Principia, and to 

 illustrate the advantages of a careful study of the 7nethods employed 

 by Nezvion, by shoiving the extent to zvhich they may be applied in 

 the solution of p7'oblems ; he has also endeavoured to give assistance 

 to the student %vho is engaged in the study of the higher branches of 

 mathematics^ by representing in a geometrical form several of the 

 processes employed in the Differential and Integral Calcuhcs^ and in 

 the analytical investigations of Dynamics.

 College. 8vo. cloth. \^s. 



Intending to make the subject accessible, at least in the earlier portions 

 to all classes of students, the authors have endeavoured to explain 

 completely all the processes which are niost useful in dealing tvith 

 ordinary theorems a7td problems, thus directing the student to the 

 selection of methods ivhich are best adapted to the exigencies of each 



problem.
