NDA Mathematics paper designed by the UPSC is not an easy paper. It takes real efforts to answer 70% of the paper correctly. It requires a lot of practice, understanding of concept and smart approach.
if you’re someone who is beginning your NDA preparation then I’d recommend you to watch this video on “How to Crack NDA”
Now, In NDA exam there are tonnes of formula for each chapter and one needs to go through all of them to have clarity.
For e.g When talking about chapter sets, apart from Operations of sets, Identities, laws, there are direct formulas such as this
Indirect Questions in NDA Mathematics
But what about the indirect formulas? In NDA you will hardly get questions from direct formulas like above. Instead, they will ask you for a particular component from the formula above and not give you the details you need according to the direct formula.
Hence, you should know all the methods and formulas to find certain answers, and therefore, you need to understand the different angles from which examiners can ask questions from a chapter in the NDA exam.
Refer to the formulas given below, it may be possible that you may not know these but had you asked n(A U B) and only certain limited information is provided, you will not be able to solve unless you have the formula given below. Also, its usage and practice questions are necessary alongside so that you remember it well. These shortcut formula also serve as tricks in a way
Further, your particular school board, such as CBSE, ICSE, or State Board, may not have included some commonly used symbols
For example, if the examiners give these options for a simple question in sets, but you don’t know what ‘/’ stands for, solving the question will become very difficult.
Similarly, every other chapter in class XI & XII has such indirect formulas and shortcut tricks. Without learning and applying them to practice questions, you’ll be overlooking a crucial aspect of preparing for the NDA
List of NDA Mathematics Formulas
Hence, it is suggested you keep notes of all the NDA formulas with you that are segregated chapter wise. If you do not have one such copy we recommend to get one prepared by the experts.
Below is the content table of NDA Formula Book
The NDA Formula Book is carefully designed to include all essential identities, laws, symbols, and formulas, along with guidelines on their application and relevant examples. This formula book not only stays with you throughout your NDA preparation but also serves as revision and reference during your 11th, 12th and IIT-JEE Preparations
