It is a common fact that students do not show much interest in solving problems in Integral Calculus when compared to that of Differential Calculus. The voluminous nature of the problems in Integral Calculus forbids the students to gain confidence in this subject.Have a look on the following discussion. A question was asked by a student and was explained by an user in the internet.Question: I have never done integration in my life and I am in the first year of university. Is it (integration) harder than taking the derivative? I've heard it just going backwards. Is it generally considered harder than differentiation? Explanation given: If you are fine with derivatives, you will be fine with integrals in I year calculus. It never hurts to pay attention in class and to do your homework1. ............ In fact, if you have trouble with a problem, you should do more of the same kind as soon as you know the answer2. ........ The kind of problems you get in first year calculus will be solvable if you learn enough tricks3. ......... Integrals start out harder than derivatives and wind up easier4...........Superscript 1 means 'Be familiar with the formulae and methods of solving problems in Differential Calculus and Trigonometry'. The formulae practice workbooks in Differential Calculus and Trigonometry (PROF MSDOSS MATH BOOK SERIES I and II ) help the students to achieve this.Superscript 2 emphasize on 'Practice! Practice!'Students gain confidence only through practice only. This can be achieved by following the methods explained in the formulae practice workbooks in Differential Calculus, Trigonometry and Integral Calculus (PROF MSDOSS MATH BOOK SERIES I, II and III ) Superscript 3: 'Trick' means 'Ability to understand and classify the problems!'The above trick is rightly followed in the above mentioned formulae practice workbooks.Superscript 4 indicates the outcome!Experience shows that the above mentioned workbooks help the students to achieve this result.Significant features :# Each unit is provided with a revision of the formulae applied and methods followed.# Self- evaluation test is provided at the end of each unit.# Already tested in India among the average and below average students with good results.# Definite integrals, evaluation of integrals using partial fraction and the remaining methods of evaluation of integrals will be discussed in volume II.Prof. M.
