First order differential equations (separable, homogeneous, linear, exact). Existence and uniqueness theorems for differential equations Linear differential equations – general theory (homogeneous and nonhomogeneous, constant and variable coefficients, undetermined coefficients, variation of parameters. Systems of linear differential equations Laplace transform and applications to solving linear differential equations Solving linear differential equations with the method of series Numerical solutions of ordinary differential equations

About the Course 
MTH 244 is the first course in Ordinary Differential Equations. We will study mathematical techniques involving differential equations used in the analysis of physical, biological and economic phenomena. Emphasis is placed on the use of established methods, rather than rigorous foundations. 
Technology

We will use the software Mathematica, which is available at URI computer labs.. 
Electronic Devices

Unless explicitly stated by the instructor during class time, all electronic devices are forbidden. This includes cellular phones, ipods and alike, ipads and other tablets, calculators, netbooks, laptops. 
Instructor's expectations 
[Based on: Zucker, S., Teaching at the University Level, AMS Notices (43), 1996, pp 863865.] 
Special Needs 
Any student with a documented disability is welcome to contact me early in the semester so that we may work out reasonable accomodations to support your success in this course. Students should also contact Disability Services for Student, Office of Student Life, 330 Memorial Union, Kingston, 8742098. 
Academic Honesty 
Students are expected to be honest in all academic work. A student's name on any written work shall be regarded as assurance that the work is the result of the student's own thought and study. Work should be stated in the student's own words, properly attributed to its source. Students have an obligation to know how to quote, paraphrase, summarize, or reference the work of others with integrity. The following are examples of academic dishonesty.

Illness 
If you become ill, notify me at 8744442 or merino@math.uri.edu of your status, and we will communicate through the medium we have established for the class. We will work together to ensure that course instruction and work is completed. We will follow regulations as stated in the University Manual 8.51.18.51.14 www.uri.edu/facsen/8.508.57.html 
Additional Information 
The University Manual (See www.uri.edu/facsen/MANUAL_08.html ) contains useful information: 8.39.1012 (attendance); 8.51.1114 (excused absences); 8.51.15 (examinations during the semester); 8.51.16 (final examinations); 8.27.1619, 8.27.1719, 8.27.1015 (plagiarisminstructor's responsibilities, judicial action, and student's responsibilities); and 8.52.10 (grading criteria). 
Civility Policy 
The University of Rhode Island has adopted a civility policy regarding disruptive classroom behaviors. Disruptive behaviors are defined as behaviors that interfere with the learning and/or teaching process. Disruptive behaviors in the classroom include inappropriate talking during lectures or class discussions or in any manner interfering with other student's ability to have a quality learning experience. Students who engage in disruptive behavior will receive one warning without penalty. Continued incidents of disrupting the class will result in the initiation of removal procedures or the loss of a letter grade. Disruptive behaviors include cell phone and pager use. Cell phones and pagers must be turned off, silent, and out of sight during classes, and you should not be checking for calls or messages during class (including "texting"). Common sense and common courtesy should govern classroom civility. 
"Incomplete" grade 
I follow to the letter the URI regulations concerning incomplete grades, namely the following paragraphs taken from the university manual:
