Mumbai University, BE in Electronics and Telecommunication, 4th Semester, Applied Mathematics-IV Papers


About the subject:

Applied mathematics is a subject that deals with the application of mathematics. The subject includes all those topics which can be useful in determining the solution of a problem through geometrical or mathematical methods. In this subject, one is taught about the various application of applied mathematics.

Examination pattern:

Like other subjects of Mumbai University, which are evaluated out of 200, applied mathematics IV is evaluated only out of 100. This means there is no practical examination, no oral examination, and no term effort in this subject.

Kind of questions:

The question paper has all kind of questions in it, Objective type as well as subjective type. Two questions in the paper are such that it has questions from almost every part of the syllabus. Remaining questions are such that they are from one or two module of the syllabus.

Paper pattern:

The question paper has all together 7 question in it. These 7 questions are asked from the syllabus of the subject and have various sub questions as sub parts. Out of these 7 questions, the students are supposed to answer 5 questions. Answering 5 questions will be sufficient for securing maximum marks. However, out of the 5 to be answered questions, one question from every section should be answered. Remaining 2 questions can be of any other section. Every question of 20 marks each, constitutes the grand total to be 100.

Time allotted:

The time duration given to the students to answer the 5 questions is 3 hours only. Or in other words the time limit is 180 minutes.
