This is an undergraduate course. In this course, students will have an idea about functional analysis. The intention of this course is to cover normed spaces, completeness, functional, Hahn-Banach theorem, duality, and operators. In addition to that, it will also discuss the Lebesgue measure, measurable functions, integrability, completeness of L-p spaces, compact, Hilbert-Schmidt and trace class operators as well as a spectral theorem in this course.


This course does not involve any written exams. Students need to answer 5 assignment questions to complete the course, the answers will be in the form of written work in pdf or word. Students can write the answers in their own time. Each answer needs to be 200 words (1 Page). Once the answers are submitted, the tutor will check and assess the work.


Edukite courses are free to study. To successfully complete a course you must submit all the assignment of the course as part of the assessment. Upon successful completion of a course, you can choose to make your achievement formal by obtaining your Certificate at a cost of £49.

Having an Official Edukite Certification is a great way to celebrate and share your success. You can:

  • Add the certificate to your CV or resume and brighten up your career
  • Show it to prove your success
