Engineering Mathematics

The engineering mathematics section may seem daunting due to its generic and
vast nature. However, it is one of the easiest sections to prepare for. The trick with this section is just to scratch the surface. No need to go deep into any of the subsections. During my preparations, I mostly concentrated on understanding the definitions of all the terms and only the most important results. Again, as in all of the GATE prep, the operative word is "understanding". Old GATE papers were more than enough for practice. Now, I will try to walk you through each section.

Mathematical Logic:

I personally did not use any material for preparation of this section. Just solved questions from old GATE papers and that was it. One only needs to understand what all the operators mean and just around 10-15 basic formulae. One can safely rely on old question papers for preparation of this section.

Probability:

For the basics any good 12th level book will do. Thoroughly understand the concepts of event, sample space, conditional probabilities. Bayes theorem is especially important. I did not cover mean, median, mode and std deviation as I was already comfortable with them. I think 12th level statistics should cover it in adequate depth. For understanding random variables and other (somewhat) advanced topics (eg. distributions), "A First Course in Probability" by Ross should be enough. Just be very selective, no need to go beyond the basics.

Set Theory & Algebra:

I studied this part from Schaum's Discrete Mathematics. One just needs to know all (around 20-30 odd) definitions and how to read the lattice diagrams.

Combinatorics:

I did not study combinatorics for this exam as I am very comfortable with the topic.

Graph Theory:

I covered all of graph theory from wikipedia and it was more than enough. Just look up the relevant articles in wikipedia and try to understand important definitions and theorems. Again, don't go in too deep.

Linear Algebra:

For the basics, stick to your 12th textbook. Do Gaussian-elimination from Gilbert Strang. For eigen values and vectors, you just need to know what they are and how to solve for them. Anywhere you can get this information is fine. I think Gilbert Strang does a good job in this area too.

Numerical Methods:

LU decomposition is part of Gaussian-elimination, and that you should have covered in linear algebra. For the rest its wikipedia all the way.

Calculus:

I did not cover this topic. Knew enough of it to answer asked questions. Mostly they stick to 12th level stuff. Anyway, very few questions are asked from calculus. You may leave this subsection (at your own risk)

Hope this helps.

Do pitch in with your comments and queries.

  1. Fantastic Mate... this gives a great view on the how to prepare for Gate Mathematics and will help people do their prep right plus also i guess help them get used to searching the internet for information on studies.(PS - you are right abt the calculus part, i missed the integration question at it cost me 2 marks which was the difference b/w maybe IIT's and NIT's for me).

  2. @enkay3987 - One can actually risk leaving out a few topics if overall prep is strong. I left out software engineering, but nothing else.

  9. hi Anshul,

    I have got offer from IIT Kanpur and IIT Delhi to do Mtech. I am a,little confused on which should i choose. I am interested in algorithms and networking. I hear that mtech in Kanpur is more research oriented . So will it be a disadvantage if i choose a course oriented Mtech in Delhi , if i am planning to do Phd Later. Also any view on the quality of faculty in Kanpur and Delhi

  10. Thanks for this section on mathematics.Since I like maths I have been spending quite a lot of time on it. Now I know that it isnt needed at all. Can you point out the subjects which needs indepth understanding. I mean subjects where we need to understand every concept given in the text.

    ReplyDelete
  11. @harishiyer Both these IITs are very very good. If you are clear that you want to puruse PhD, then there is no such thing as a course oriented M.Tech. Just make this very clear to your professors. Try to interact a lot with them and they will go out of the way to encourage your interest in research. So, don't base your decision on such a flimsy argument. Evaluate both the departments on basis of research that is coming out from them. Google scholar and microsoft academic search are your best friends.

  39. You need to manage your time with solving mathematics questions and answers. Some students fear due to maths questions, But we should not do this type of work. Only focus on your study with fully concentration.
