OBJECTIVES:

  • To make the student acquire sound knowledge of techniques in solving ordinary equations that model engineering problems.
  • To acquaint the student with the concepts of vector calculus needed for problems  in all engineering disciplines.
  • To develop an understanding of the standard techniques of complex variable theory so as to enable  the  student  to  apply  them  with  confidence,  in  application  areas  such conduction, elasticity, fluid dynamics and flow the of electric current.
  • To make the student appreciate the purpose of using transforms to create a new domain which it is easier to handle the problem that is being investigated.
