Engineering Mathematics I (010.140.005)

 

Spring  2007

 


 

Description

 

Most practical problems involved in engineering can be formulated and solved mathematically. Engineering Mathematics I, II, and III introduce undergraduate students to those areas of mathematics which, from a modern point of view, are most important in connection with such engineering problems. In particular, this course, Engineering Mathematics I, emphasizes the ordinary differential equations which are used to describe the physical situations of such engineering problems. This course is also required for Engineering Mathematics II and III.
