Hello friend today I will express my views on RD sharma book RD sharma book is a best book for me I had bought the book last year for class 10 board exam I am still reading it. Its price is little bit high but I guaranteed that by reading it you will never get less marks I am so happy by using itSo refer everyone to buy it because it is so useful for those student who are going to face board examUnfortunately there are no books of R D Sharma for Engineering mathematics. He writes book only for Class XI and XII classes which is published by Dhanpat Rai Publications.If you are looking forward for lucid and good books for engineering mathematics ( for first four semesters) , you can see Gorakh Prasad and B S Grewal. Gorakh prasad’s Calculus ( Integration and Differentiation) books will help you in first and second semester. After that B S Grewal is really wonderful book.I agree with this book I know it Is too lengthy but practice make man perfect so buy it and get good marks in board exam
