How can I prepare for Trigonometry for JEE?

Another great article by Harish. This one focuses on how he studied for trigonometry and what he feels is an optimal way to prepare. I have duly edited the post along with a few personal comments from my preparation. All of my comments are in Italics.

If you want to study trigonometry, here is my method in detail, in proper order as it were.

  • Write, write and just write down all the important formulae in a seperate note book.
  • Read, read and read all the formulae until and unless you get a complete grip over each and every formula. Essentially, this is just the way you would memorise other things. So if you have an alternate memorisation technique, then that works too.
  • Solve, solve and completely solve all sorts of sums that are up for grab. And this definitely helps. Trigonometry is a chapter where practice is a very crucial factor.
  • Draw, draw and always draw a triangle irrespective of what the question is. This is a nice interesting approach to trigonometry. However if you have gotten the hang of the thing and are able to visualise without drawing triangles, then you can and should just do this step mentally to save precious time.
  • Think, think and stretch the limits of your brain and think as to which formula needs to be applied for which sum. Ideally speaking, there can be multiple formulae and approaches to trigonometry questions. However some formulae provide easier and quicker solutions. Practice more so that you are able to recognise these patterns.

Trigonometry is a chapter where application of formula is really important for which it all boils down to solving of sums.

Coming to the books, I used only Cengage book apart from FIITJEE material,and it is pretty good (infact all Cengage Maths books are pretty good (I haven’t tried Calculus though)). About SN Loney, though I bought that book, I never used it. Totally your choice.

Here are the book links. Please support Prepsera by buying from these links. This matters and helps in keeping the site alive.

Hope it helps.

All the best!

What exactly is the difference between a 150-200 or 250-350 marks scorer

Thanks a lot to Harish for allowing me to borrow this amazing piece. The base of this article is written by Harish and has been supplemented with quite a few edits from my side.

KVPY Stage 2

Guys, could you keep me informed on this blog post about when the KVPY Stage 1 shortlist comes and the potential interview dates?

There are a few things I want to tell you about interviews.

Meanwhile, anything that you want to read about? I would write about that

Why?

A word of immense power. A word that makes humans different from other animals. A word that, sadly, humans are afraid to use to their full potential.

Why has power… Beyond compare. And yet, we don’t use it. Think about it… Deeply.

What next for Prepsera?

When I started this blog around a year ago, I had a lot of reasons for it… I wanted to share my feelings about exams, about how to keep yourself in good shape, about how exactly to go forth in life, etc. I was hoping that I might get an audience big enough to voice my views out to everyone, to tell students that exams are not the end of the world, to tell parents that JEE isn’t the only thing that matters, and to tell the determined souls how they could prepare better.

Test of Reasoning by Edgar Thorpe : Perfect for NTSE, CAT, Bank PO and more

Welcome all to the book review of this wonderful book – Test of Reasoning by Edgar Thorpe. This has been one of the best books I have used on this subject and I can tell you that I absolutely fell in love with solving it’s problems. A great testament to this book is that it really sharpens your mind. For example, during my NTSE preparation, I exclusively practiced from this book for the Mental Ability portion of the exam. Funny thing, though. The year I cleared NTSE was perhaps the first time that there were more scholarships available than the eligible candidates. Basically, 1000 kids were supposed to get a scholarship that year but only 750 managed to pass in the mental ability test. This lead to only 750 kids being awarded the scholarship. That was because of an extremely tough MAT paper (was of a CAT level). All I have to say that is thanks to this book, I did manage to clear the mental ability paper with ease.

MacOS : Thou art a piece of beauty (So are you, Win 10)

I suppose the article should be self evident. But for those who still didn’t get it, I am seriously impressed by MacOS as well as Windows 10. Never thought I would be saying this, though. For me, desktop OSes were always a quagmire of never ending issues : Windows with it’s viruses and blue screen of deaths and Mac which I used to find complicated and ugly. Only a  few years later, now I am in serious love with both the Operating Systems. The only loser out here seems to be Linux which is great for coding and stuff but pretty pointless otherwise.

KVPY, 2017 : A last minute checklist for all students

Finally, the exam approaches. No need to worry, though. I’m sure you all are well prepared (even though you feel you haven’t prepared as well. Trust me, it’s a feeling that every candidate faces sometime or the other and is completely natural). Time seems to be of extreme importance here so I’ll quickly dive into the basics.

Motivation is one of the keys to success… And other important things to note

Do you know how people achieve success in their life? It’s cuz they are doing the thing for the interest of it and not for the heck of it. Most people are motivated to make something or to do something and that’s what fuels them to achieve. So, the take away message is that do a thing only if you want to.

How does an International Maths Olympiad (IMO) Medalist Advise You To Prepare for the IMO…

So, I had a quick discussion with my friend Shourya Pandey, a bronze medalist at the International Maths Olympiad, about his views on the exam and what all stuff he would like his juniors to know… Excited about it? You should be! Let’s head on and have a look at what Shourya advises :

Inorganic Chemistry : Part 1

Wanna know the secret to an awesomely insane rank ? Well, Inorganic Chemistry is the answer. Don’t be surprised… Read on…

To Make it easier for you to study inorganic chemistry, we have divided it into three parts: In this part, we shall talk about those chapters of inorganic chemistry that need understanding of concepts mostly and hardly any rote memorization. These are – Periodic Table, Chemical Bonding, Coordination Compounds and Metallurgy.

Algebra : Theory of Equations, Matrices and Complex Numbers (mainly)

Algebra… The study of the one and only ‘x’, the ever unknown variable. Just kidding, algebra is much more than just all this. Although many books differ in what they classify algebra as, I am going to use algebra to basically cover the theory of equations, complex numbers, matrices, sequences and series, and a few minor chapters. Time’s of prime importance and so, let’s be on our way to discuss this essential unit of JEE-Mathematics syllabus.

Calculus 202 : Integral Calculus for JEE-Main and Advanced

Let’s head up to the second portion of the Calculus portion of JEE Syllabus. The tricks that we have mastered and used while doing the differential part of calculus shall help a lot in Integral Calculus. After all, Integration is just the inverse of Differentiation. However, it gets a bit more interesting than that. Differentiation of functions can be easy, sometimes even implicit. However, Integration for the most part is not elementary. Let’s head on to the individual chapters and the books that we are going to need for this high-weightage unit of JEE Maths syllabus.

Organic Chemistry – Nucleophilic Substitution – Alkyl Halides

I will be very honest with all of you. I didn’t start my journey of organic reaction mechanisms with the standard method. Usually, kids start of mechanisms with Hydrocarbons (addition/free radical substitution, etc). I started my journey of Reaction Mechanisms with Nucleophilic Substitution reactions. The chapter was Alkyl Halides and there were a number of concepts to be learned – Sn1, Sn2 and Sni reactions, along with the use of Neighbouring Group Participation (NGP). These are definitely the OST important concepts of this chapter and enough attention must be given on them.

Mechanics – The most conceptual part of JEE Physics

Mechanics is undoubtedly the most conceptual part of JEE Physics. In fact, the entire two year syllabus revolves around mechanics. While the exam paper has about 30% direct questions from mechanics, it is safe to assume that the paper also has another 30-35% questions indirectly involving mechanics. That’s a whopping 60-65% of the paper based on one single unit of Physics! Basically, what this means for you, the candidate, is that an absolute mastery over Mechanics is essential for a good rank. Also, keep in mind that mechanics CANNOT be mastered in a month… it needs about 8-10 months of rigorous practice to fully grab the concepts of mechanics. So, if initially, you cannot understand mechanics or solve its questions, don’t be disheartened. Most of the kids have trouble understanding mechanics.  Continue reading Mechanics – The most conceptual part of JEE Physics
