PREFACE 



This little book of problems is offered as a system of exerc 

 suitable for use with any of the available textbooks or with a 

 lecture course. Most of the problems have been used in the classes 

 of the author. A novel feature is the stating of the time needed 

 to perform the actual solving of each problem. This should prove 

 useful not only to the instructor in the assignment of problems, 

 but also to the student as a measure of his own speed. In most 

 of the problems the time given is that which was actually used by 

 an undergraduate student. It will, however, probably be found 

 necessary to allow more time to the average class than is here 

 indicated. 



Sheets giving the answers to the problems will be provided in 

 such quantities as may be needed, but only to instructors.
