Prerequisites

Calculus 2 or the permission of instructor.

Attendance

Since the course is mostly based on material covered in class handouts, it is absolutely imperative that students attend all classes. Students are responsible for all material covered in class, even if attendance is not checked or assignments collected.

Exams

There will be three semester exams and a cumulative final exam. No makeup exam will be given unless the excuse for missing the scheduled exam is acceptable to the instructor. Any makeup exam must be taken before the next regularly scheduled exam. No exam grade will be dropped.

Assignments and Projects

There will be three assignments and three Matlab projects during the semester. There will be no makeup assignments. Assignments or projects turned in after their due date will receive an automatic reduction in grade. No assignment or project grade will be dropped.

Course Objectives

  • solve differential equations using various techniques.
  • identify situations that require the use of differential equations, develop mathematical models involving differential equations and justify their solutions.
  • use appropriate technology to find and examine solutions of differential equations.

Learning outcomes

Students will:
  • demonstrate the proficiency in solving differential equations;
  • acquire knowledge of various mathematical concepts and models involving differential equations;
  • acquire knowledge of modeling techniques required for successful application of mathematics;

  • know how to use appropriate technology and mathematical software to solve problems involving differential equations.

Academic integrity

Academic integrity is at the center of the educational experience at USciences. Students are therefore expected to uphold the highest standards of academic integrity and not engage in or tolerate academic dishonesty. Academic dishonesty includes, but is not limited to, fabrication, cheating or plagiarism. Any violation of academic integrity will be investigated and, where warranted, the student will receive appropriate sanctions through the University's Student Conduct Process. Please familiarize yourself with the current USciences Student Handbook. Adheren ce to the Student Conduct Policy and Academic Integrity Policy will help to ensure that your learning and living experiences are founded on integrity.
