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!

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.

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

Calculus 101 : Differential Calculus

The Case with Differential Calculus :

Do you like to watch the skateboarding competitions?Where do you find the thrill, in the skating on the flat ground or on the curved part?

Just for a moment…. rewind the skateboarding video that you are watching alongside as you read this article…. and observe the motion of the head of the skateboarder? Do you see that for very short time intervals, the head moves approximately as a straight line? 

Did you know that simple mathematics can help you calculate the tilt of this ‘line’ (something we call the slope)? If not, then differential calculus is the way to go. Finding the slope is one of the basic tasks that differential calculus deals with. That is not all, however. Differential Calculus is a much more diverse and beautiful science which explains a lot about the world. In fact, all the major researchers in the world use calculus extensively. Simply speaking, calculus is the most logical and useful part of mathematics, specially in JEE syllabus. Continue reading Calculus 101 : Differential Calculus

Modern Physics : Quick, simple, and easy

Everyone knows what modernity stands for, right? Speed. Yup, that’s the answer. And how do we achieve it…. Well, we use short cuts, tricks, slangs, etc. Everyone knows what “IDK’ stands for, right? Such a long line….shortened into three letters. Yeah, that is the new modern generation. Quick, fast and short. Presenting the shortest unit of the enitre JEE syllabus, something as short as its modernity and as quickly understood… Yup, you guessed it right. It is none other than Modern Physics, the most scoring unit of JEE Physics. Continue reading Modern Physics : Quick, simple, and easy

Inorganic- The better way to prepare

Inorganic. This word is lodged deep inside in the psyche of a JEE Aspirant. As soon as the ears hear an “in-” a chill hurtles down his spine. Relax, inorganic is a wolf in a mammoths skin. The course is not very specific and information available is enough to boggle anyone who attempts to mug it all up. What we need is a reliable information source and then, a method to organize the information so that we can retain it more efficiently. Let’s first talk about the source:-
