Mathematics-IV (Maths 4) Notes and PYQs for AKTU B.Tech
Mathematics-IV is the second-year AKTU mathematics paper. For CSE and allied branches it typically covers partial differential equations, applications of PDEs, statistical techniques (curve fitting, correlation and regression), probability distributions and numerical methods, depending on the branch scheme. It is a numericals paper, so marks depend almost entirely on practice.

mathematics-iv study guide
This page collects every Mathematics-IV resource on AcademicArk for AKTU second-year (Semester 3 and 4) students: 21 PDFs in total, including 8 typed notes sets and 13 previous year question papers. Each resource opens with a preview, and the list is ordered by what students have recommended, downloaded and viewed most.
The Maths 4 syllabus is divided into 5 units: Unit 1 (Partial Differential Equations), Unit 2 (Applications of PDE and Fourier Transform), Unit 3 (Statistical Techniques I), Unit 4 (Statistical Techniques II) and Unit 5 (Statistical Techniques III).
AcademicArk has analysed 10 AKTU Maths 4 question papers from 2021 to 2026, covering 235 questions. Unit 4 (Statistical Techniques II) carries about 30 marks per paper, while Unit 2 (Applications of PDE and Fourier Transform) carries about 29 marks per paper. The most repeated topics are Heat and Wave Equations (asked 37 times), Statistical Tests of Significance (asked 22 times), Probability and Random Variables (asked 20 times) and Measures of Central Tendency (asked 18 times). The full unit-wise breakdown, important questions and a predicted paper are linked in the exam intelligence card on this page.
Work through previous year papers rather than only notes: AKTU Maths-IV repeats question patterns closely. Practise PDE solution methods, method of separation of variables, curve fitting by least squares, correlation and regression problems, and standard distributions (binomial, Poisson, normal). Time yourself, because long calculations are where students lose marks.

Frequently asked questions
How do I score well in AKTU Maths 4?
Solve previous year papers unit by unit. Maths-IV repeats question types closely, so practising PYQs is the fastest way to a good score.
Which units of Maths-IV are most scoring?
Statistics and probability problems are usually the most predictable. PDE questions carry high marks but need more practice.
Are Maths 4 previous year papers available?
Yes. This page lists Mathematics-IV previous year question papers together with notes, and the exam-intelligence card shows which topics repeat.
How many Maths 4 previous year papers has AcademicArk analysed?
10 AKTU Mathematics-IV papers from 2021 to 2026, with 235 questions mapped to units and topics, so you can see exactly what repeats before the exam.
Which unit of Maths 4 is most important for the AKTU exam?
Based on previous year papers, Unit 4 (Statistical Techniques II) carries the most weight at about 30 marks per paper. The topics that repeat most are Heat and Wave Equations, Statistical Tests of Significance and Probability and Random Variables.
