MA 387 - Partial Differential Equations

3 lecture hours 0 lab hours 3 credits
Course Description
This course provides a smooth transition from a course in elementary ordinary differential equations to more advanced topics in a first course in partial differential equations, with heavier emphasis on Fourier series and boundary value problems. Topics covered includes separation of variables, classification of second order equations and canonical form, Fourier series, the one-dimensional and two-dimensional wave equation and heat equation, and Laplace’s equation. It also covers some applications, such as vibrating string, vibrating membrane, vibration of beams, heat conduction in bars and rectangular regions, etc. (prereq: MA 235 , MA 232  or MA 2323 )
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
  • Write Fourier series of functions with period 2p
  • Write Fourier series of functions with arbitrary periods
  • Be able to write Fourier series of non-periodic functions using half-range expansions
  • Write the complex form of Fourier series
  • Solve one-dimensional wave equation using method of separation of variables and apply it to vibrating strings
  • Solve one-dimensional heat equation using method of separation of variables and apply it to heat conduction in bars
