i Introductory Letter Dear Student, We congratulate you on joining USOL and hope you will enjoy association with our Institute. It is our endeavour to make this association meaningful and a great learning experience. As you know you are now in the first semester of B.A. Mathematics, you are encouraged to solve exercises of this book as well as from other standard text books at your own instead of finding solutions from the help books. This block of lessons deals with the elementary calculus of single real variable. You will find in this block of lessons a detailed discussion on all the topics and their applications. The exercises given at the end of each lesson deal with the topics discussed in the text and are sufficient for practice and for examination point of view. Please go through them very carefully. If you have any difficulties do not hesitate to write to us or to visit us personally. Yours sincerely Deptt. of Mathematics
