Average Course Rating

(3.46)

This is a course in ordinary differential equations (ODEs), equations involving an unknown function of one independent variable and some of its derivatives, and is primarily a course in the study of the structure of and techniques for solving ODEs as mathematical models. Specific topics include first and second ODEs of various types, systems of linear differential equations, autonomous systems, and the qualitative and quantitative analysis of nonlinear systems of first-order ODEs. Laplace transforms, series solutions and the basics of numerical solutions are included as extra topics. Prerequisites: Grade of C- or better in 110.107 or 110.109 or 110.113, or a 5 on the AP BC exam. Area: Quantitative and Mathematical Sciences.

Fall 2012

Professor: Richard Brown

(4.23)

The best aspect of the course was the enthusiastic and engaging professor who was able to teach the important concepts of the class and provide extra assistance for students. The worst aspect of the course was the heavy and time consuming workload. The homework assignments were lengthy, repetitive, and sometimes did not correlate with what the students were learning in class. The course would improve if the homework problems were slightly reduced, if more time were spent on the more difficult content, and if students were provided with more examples or practice exams that would help them master the material. Prospective students should know that some prior knowledge of linear algebra and advanced calculus is needed to be successful in this course. Students who attend lectures, do the problems, and seek extra help when needed wil perform wel in this course.

Fall 2013

Professor: Carl McTague

Some students praised the instructor for providing many examples of topics students were learning which aided their ability to master the course’s topics. Some students found the course’s homework and problems set to be hard and thought they took up too much time. Suggestions for improvement included providing additional support either by the instructor providing additional practice problems or support with problems. Prospective students should know that the material is tough but manageable and in line with other courses. Students found it useful to sit towards the front of the classroom as the instructor was soft spoken.

Fall 2014

Professor: Hans Lindblad

(2.85)

Reflecting on this course, students said they appreciated the usefulness of the subject matter and its applicability to other areas. Many students found the professor to be difficult to follow. Students felt that the course could be improved by making the final exam count for a smaller portion of the final grade. Students wanted other potential attendees for this class to know that completing homework assignments was important to preparing for the exams.

Spring 2013

Professor: Lu Wang

(2.54)

The best aspects of the course included the teaching assistants who were good at clarifying and explaining the material to some extent. The worst aspect of the course was the dul lectures that were difficult to understand because of the professors’ accent. The textbook did not supplement the course well, and students found the material very challenging. The course would improve if the professor was clearer in delivering the content, if there was more review on the subjects, and a better supplemental textbook. Prospective students should endeavor to do their homework assignments in order to get practice with the problems, and should prepare to put in some extra time with this somewhat challenging course.

Spring 2014

Professor: Lu Wang

(2.63)

The high points of this course were the useful nature of the subject matter in terms of real world applications, and the help from the TAs to understand the concepts. The lowest ratings were given to the instructor. Many students found that they did better learning on their own and had a hard time reaching her for additional help. Suggested improvements to the course centered on a more effective instructor, and more example problems during class. Prospective students should know that the workload is heavy, but the material is useful. Students from this course recommend finding a different instructor.

Spring 2015

Professor: Jiuyi Zhu

(3.64)

The best aspects of the course included the interesting and useful material, the professor’s clear and systematic teaching style, and relevance of class lectures and homework assignments to the exams. Students also appreciated the professor’s review sessions before tests. Many students found the homework to be long and tedious, and others had difficulty understanding the professor during lecture. This course could have been improved by al owing for more error on exams by including more than 5 questions or allowing partial credit. Prospective students should know that they should take linear algebra and Calculus II before Differential Equations.
