• Number of Credits: 3
• Prerequisites: Permission of the Graduate Committee
• Lutful Bari Bhuiyan
• Office: C-317 (ext 4775)
University of Puerto Rico - Rio Piedras Campus
Department of Physics

### Text

• Mathematical Methods for Physicists , 6th edition, George B. Arfken and Hans J. Weber (Elsevier, Academic Press)

### Instructional Strategy

• Lectures

• Grading will be based on four exams each of which will have the same weight. At least two of the exams will have take home components that need to be handed in within a specified period. The exams will constitute 75% of the total Grade, while the remaining 25% will be based on a numerical project.
• Problems in the exams will be based on the material covered in the class, examples worked out in class, suggested problems, and exercises given throughout the course.
