About the course: In this course you will learn some mathematical methods that will help you find the solutions to some engineering problems. For example: you will learn about the algebra of complex numbers; matrices and determinants and how to apply these concepts to solve linear systems of equations. You will also learn exact methods for solving 1st. and 2nd. order differential equations including their applications. By the end of the course you will be able to solve linear systems of ordinary differential equations.

Topics:

• Complex Numbers and Functions:   complex numbers, complex plane; polar form of complex numbers, powers and roots; exponential function.
• Linear Algebra: Matrices, Vectors, Determinants, Linear Systems:   matrices, vectors: addition and scalar multiplication; matrix multiplication; linear systems of equations, Gauss elimination; linear independence, rank of a matrix, vector space; solutions of linear systems: existence, uniqueness; determinants, Cramer's rule; inverse of a matrix, Gauss-Jordan elimination.
• First-Order ODEs:   basic concepts, modeling; geometric meaning of y'=f(x,y), direction fields; separable ODEs, modeling; exact ODEs, Bernoulli equation, population dynamics.
• Second-Order Linear ODEs:   homogeneous linear ODEs of second order; homogeneous linear ODEs with constant coefficients; modeling: free oscillations (mass-spring system); Euler-Cauchy equations; existence and uniqueness of solutions, Wronskian; nonhomogeneous ODEs; modeling: forced oscillations, resonance; modeling: electric circuits; solution by variation of parameters.
• Higher Order Linear ODEs:   homogeneous linear ODEs; homogeneous linear ODEs with constant coefficients; nonhomogeneous linear ODEs.
• Systems of ODEs. Phase Plane. Qualitative Methods:  basic of matrices and vectors; systems of ODEs as models; basic theory of systems of ODEs; constant-coefficient systems,phase plane method; criteria for critical points, stability; qualitative methods for nonlinear systems; nonhomogeneous linear systems of ODEs.

Prerequisites:  MTH 142

Policies: You are expected to abide by the University's civility policy:

"The University of Rhode Island is committed to developing and actively protecting a class environment in which respect must be shown to everyone in order to facilitate the expression, testing, understanding, and creation of a variety of ideas and opinions. Rude, sarcastic, obscene or disrespectful speech and disruptive behavior have a negative impact on everyone's learning and are considered unacceptable. The course instructor will have disruptive persons removed from the class."

Cell phones, IPods, beepers and any electronic device must be turned off in class.

You are required to do your own work unless specifically told otherwise by your instructor. In support of honest students, those discovered cheating on assignments or exams will receive a grade of zero on the assignment or exam. Use of unauthorized aids such as cheat sheets or information stored in calculator memories, will be considered cheating. The Mathematics Department and the University strongly promote academic integrity.

• Exam I                                     : 100pts
