Transform Calculus and its applications in Differential Equations

Indian Institute of Technology, Kharagpur and NPTEL via Swayam


For undergraduate students in the discipline of Mathematics, the course on Transform Calculus has become an integral part. This course is designed to train students with the basic Integral Transform techniques.Application of these transforms techniques in solving ordinary differential equations and partial differential equations will be discussed. We will also introduce some higher level concepts that will prepare them for future research and development projects. The course outline is given for each week. We will introduce each topic and give an overview of the topic and underlying theory. This will be followed by some solved numerical examples on each topic for their better understanding. Weekly assignments will be provided and graded
INTENDED AUDIENCE : MATHEMATICS(Any student with a course in Mathematics in their curriculum)PREREQUISITES : NONEINDUSTRY SUPPORT : NONE
