A Good Lesson Plan is instrumental for the delivery of course content in a competent way so that students get benefited in view

of learning, developing good skill set, updating with current trends in industry etc., Delivery including latest trends in the technology

and applications brings deep insight of the course in students. As the plan includes the home assignments, quizzes, course projects

etc., it carries out the continuous assessment of student learning (course outcomes).

1. PREREQUISITES

Integral and Differential Calculus


(Objectives define the importance of course and how the course is helpful to the students in their career.

Objectives must be defined first and contents must be developed later.)


• Computing Fourier coefficients.

• Understand the properties of Fourier transforms.

• Apply method of separation of variables to solve partial differential equations.

• Apply Cauchy’s theorem, Cauchy’s integral formula and residue theorem to evaluate complex intregation.


(Outcomes define what the student will be able to do upon completion of the course. Course outcomes must be

assessable. The blooms taxonomy terms are used as reference in defining course outcomes)


• Solve problems using Fourier series.

• Evaluate problems involving Fourier and inverse Fourier transforms.

• Solve the second order linear partial differential equations by method of separation of variables and Fourier series.

• Evaluate line and contour intregals.
