                                           Calculus I (Math 241)
                                                     (In Progress)
                     ThefollowingisacollectionofCalculusI(Math241)problems. Studentsmayexpect
                  that their final exam is comprised, more or less, of one problem from each section, or
                  one that is similar. To the instructors the collection indicates what will be expected of
                  the students in the common final.
                     The course will cover more material than what is reflected in the problems. In
                  particular students shall develop a conceptual understanding for calculus in addition to
                  learning how to solve problems as below. Still, being able to solve the problems (closed
                  book and in a clear and transparent manner) will be an indication that you have a firm
                  grasp of the course material.
                     On the exam no calculators will be allowed. If you insist on a decimal-numerique
                  answer, then you may use a simple scientific calculator in your practice (not graphing
                  and not symbolic). The solution for each problem has to include enough work to show
                  how it was derived. If there are errors in the work, you may not receive credit, even if
                  the final answer is correct.
