Course description.
Linear ordinary differential equations, Laplace transforms, systems of equations, and applications.
Differential equations are used to model many physical phenomenon. We will introduce classical techniques for solving differential equations; in addition, we will also very briefly touch upon the use of modern computational software in solving differential equations.

MATH 122 or MATH 142, or MATH 126 or MATH 146 with grade of C- or higher; previous or concurrent enrollment in MATH 290 or MATH 291 recommended. Not open to students with credit in MATH 320.  


Introduction to differential equations
Octave and direction fields and numerical methods
First order differential equations
Second order differential equations
Laplace Transforms
Systems of first order differential equations

There are no possibilities for make-up quizzes or midterms; if you have a legitimate excuse for missing an exam (for example, medical reasons), then the absense will be excused without penalty; in the case of quizzes, your other quizzes will simply be worth more, and in the case of a midterm, your final exam will be worth more.

Textbook: Boyce and DiPrima (any edition).
