Walk-in tutoring for math is located in rooms 201 and 205 in Lippitt Hall (Kingston) Monday through Thursday from 1:00 - 9:00. There is a no appointment needed and it is FREE. There are laptops available so you can access Mathematica. Be sure to bring your notes and questions with you. The tutoring center is a great place to study with classmates and friends, prepare for exams, and review the material covered in lecture.



Mathematica is a powerful Computer Algebra System (CAS) that can perform the most complicated calculations and draw spectacular graphics at the touch of the button. Knowledge of software like Mathematica will help you in your future professional career as well as in understanding material in calculus and calculating solutions to computationally complex problems.

Dr. Pakula's website for Mathematica has links to introductory videos and basic worksheets. The Main Library (Kingston Campus) and the Memorial Union computer labs will have computers with Mathematica installed on them. Lippitt Hall 205 also has laptops with Mathematica installed on them. Furthermore, you can get a student version for free. Click here for instructions.

There will be one project where you will be required to use Mathematica.

Course Description
MTH 244 is an introductory course in Differential Equations for students of science, computer science, engineering, mathematics, and others. It is a challenging course in the STEM disciplines. Students will learn skills needed for solving differential equations and will learn how to use differential equations to model physical phenomena. The material in this course provides a foundation for further study in applied mathematics, physics, engineering, chemistry, biology, and many other areas of science.


You are expected to attend lectures, keep up with the corresponding reading in the textbook, and work through the assigned homework problems.

You are expected to get notes and any announcements of any classes you must miss from other students before the next class. Remember, not being in class does not excuse you of responsibility for the material covered that day.

You will be expected to solve some differential equations by hand, approximate solutions of differential equations using technology, and use differential equations to model physical phenomena.

Classroom Policies

Attendance is required, please arrive on time. If you miss class, you must notify me ahead of time via email. See the policy on Make-up Work.

At times, you will be expected to participate in class and to practice problems as a class. Be respectful of others in the classroom. No mobile phones, ipods, or any other personal electronic devices are allowed during class.

Illness Due to Flu
The nation is experiencing a widespread influenza-like illness. If any of us develop flu-like symptoms, we are being advised to stay home until the fever has subsided for 24 hours. So, if you exhibit such symptoms, please do not come to class. Notify me of your status, and we will communicate through email, at We will work together to ensure that your questions regarding the material are answered and that you have a proper amount of time to complete your assignments.

The Centers for Disease Control and Prevention has posted a few simple methods to reduce the transmission of the flu virus. These include: covering your mouth and nose with a tissue when coughing or sneezing; frequent washing or sanitizing of your hands; avoiding touching your eyes, nose, and mouth; and staying home when you are sick. For more information please view or The URI Health Services web page,, will carry advice and local updates.

Make Up Work
If you miss class, you must notify me ahead of time via email. If you do not notify me ahead of time, then you cannot make up the work and you will receive a zero for the assignment. If you cannot take a midterm exam at the regularly scheduled time, you must notify me ahead of time. Otherwise, you will not be allowed to re-take the exam and will receive a zero. Obviously, exceptions will be made in the case of an emergency. However, “I woke up and didn’t feel well” does not constitute an emergency – you need to send an email in a situation like this.

Students With Disabilities
Any student with a documented disability should contact me as soon as possible to discuss your accommodations. Students should also contact Disability Services for Students: Office of Student Life, 330 Memorial Union, 874-2098. They will determine with you what accommodations are necessary and appropriate. All information and documentation is confidential.

Cheating is defined in the University Manual section 8.27.10 as the claiming of credit for work not done independently without giving credit for aid received, or any unauthorized communication during examinations. Students are expected to be honest in all academic work. The resolution of any charge of cheating or plagiarism will follow the guideline set forth in the University Manual 8.27.10 – 8.27.20.
