# MTH 4465 DIFFERENTIAL EQUATIONS COURSE PROCEDURE

## MTH 4465 DIFFERENTIAL EQUATIONS

### 3 Credit Hours

#### Student Level:

This course is open to students on the college level in the sophomore year.

#### MTH4465 ‐ Differential Equations (3 hrs.)

Techniques for solving ordinary first and second order differential equations, Laplace transforms, Eigen values, and approximation techniques. This course requires that the students furnish their TI‐89 or TI‐

92 graphing calculator. Prerequisite: Minimum grade of C in MTH4455 Calculus III.

Lecture

#### Prerequisite:

Minimum grade of C in Math 4440 CALCULUS II

#### Controlling Purpose:

To equip science and pre‐engineering students with a knowledge of advanced methods in solving differential equations and systems of differential equations.

#### Learner Outcomes:

Students will learn to solve ordinary linear differential equations by various methods, including simple approximation techniques and Laplace transforms, and be introduced to solving systems of these equations using Laplace transforms and matrix techniques.  Technology will be used to a modest extent.

Projects Required:  None

#### Text Book:

Contact the Bookstore for current textbook.

#### Materials/Equip:

Computers will be available to the student in the Computer Lab.  Students should provide their own graphics calculators such as a TI‐89 or TI‐92 especially.

#### Attendance Policy:

Students should adhere to the attendance policy outlined by the instructor in the course syllabus.

The grading policy will be outlined by the instructor in the course syllabus.

#### Maximum class size:

Based on classroom occupancy

#### Course Timeframe:

The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college. A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally‐established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out‐of‐class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time. The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face‐to‐face format.
