A Text Book Of Differential Equations BA and BSc 3rd Semester PU

 S Dinesh & Co. presents O P Arora's book on the second paper of BA 3rd Mathematics.

As the Mathematics has three papers according to the Panjab University, Chandigarh, here the content of the book is for the second paper Differential Equations 1:

• based on the syllabus of Panjab University Chandigarh
• syllabus or exam ( mark )pattern layout
• latest previous year question papers   
• detailed and various explanation of approach to solve problems 
• important question are discussed after the end of each chapters
