I have seen that in limits we have to multiply and divide by some unknown nos. which I have no idea. I am able to solve some questions but still it is a problem. Sometimes I have to divide by the exponent,subtract by 1,take the term as y,rationalize. It is frustrating. Can you give me some tips.

Hi Shrey, It depends upon question to question that by which number we are multiplying and dividing. You will get the hang of this thing when you will solve good quality and quantity of question. There are some types given in the study materials and books. You should take a look at them. Hope it helps. ATB. Amit Jain B.Tech IIT Delhi AskIITian Faculty
