Functions completed including sheet discussion. Inverse trigonometric functions theory completed and nearly 50% sheet also complete. I will start limits from Tuesday. I have shared its introductory lecture to the batch students. Now I can say the real calculus begin, nearly all topics of calculus have dependence on limits. If you don’t develop a good approach on solving limits efficiently, then you are going to face a lot of difficulty. Mostly students having poor command on limits use L Hospital’s rule to solve limits which is a method to used in few problems only. I teach this method after taking limits, continuity, differentiability and differentiation.
