PREREQUISITE: Math 241
COREQUISITES: PHYS 201 and ENGR 122
COURSE GOALS: The student will become proficient in integration of single variable functions. In addition the
student will master techniques for solving first and second order differential equations with constant coefficients and
initial conditions. This proficiency will be demonstrated by satisfactorily completing a series of exams and
homework assignments.
TEXTBOOKS: Calculus: Concepts and Contexts by James Stewart, Notes on Differential Equations and Statistics
by B. Schröder, and A Custom Companion to Calculus by Thomson Learning
COURSE OUTLINE AND OBJECTIVES: The details are attached. To be covered are Concepts Sections 4.9,
5.1-5.8, 6.1, 6.2, 6.5, and 7.2; Custom Companion Sections 10.1, 19A-C, and 20B; and Modules EXB, FIR, LDT
and LDλ in the Notes on Differential Equations and Statistics
ATTENDANCE REGULATIONS: Class attendance is regarded as an obligation as well as a privilege. Attendance
and class participation are mandatory. It is the student's responsibility to keep informed of any announcements,
syllabus adjustments or policy changes made during scheduled classes. Notify the instructor in advance if you must
miss class, arrive late for class, or leave early from class.
GRAPHING CALCULATOR: A graphing calculator that does at least as much as the TI-82 and access to
Mathcad will be required for the course, but TI-92 is not allowed. Graphing calculator is not allowed for all tests,
a regular scientific one is optional.
EXAMINATIONS & Makeup Policy: There will three topical exams and a comprehensive final exam. If you
have to miss an exam, you must notify the instructor prior to the exam either in person or by phone. An unexcused
absence from an exam will result in a zero on that exam
Homework: For homework hand-in dates and assigned problems, please consult the included schedule of classes.
GRADE DETERMINATION POLICY: The grading scale will be: A = 90% - 100%; B = 80% - 89%; C = 70% 79%; D = 60% - 69%; F = 0% - 59%. The course grade will be calculated as follows:
Exams 1--3
Homework
Final
Total
60% (20% each)
. 10%
30%
100%
STUDENTS NEEDING SPECIAL ACCOMODATIONS & RETENTION OF GRADED MATERIALS:
Students needing testing or classroom accommodations based on a disability should discuss the need with the
instructor during the first week of class. In the event of a question regarding an exam grade or final grade, it will be
the responsibility of the student to retain and present graded materials which have been returned for student
possession.
Academic misconduct. In accordance with p.30 of the Louisiana Tech University bulletin, any form of plagiarism
is considered academic misconduct and will carry a minimum penalty of an “F” for the assignment in question. The
instructor reserves the right to enforce a more stringent penalty.
