What course are functions and operators (eg differential operator) introduced?

• Courses
In summary, the speaker is about to start a graduate program in signal processing and has been browsing literature that uses operators on functions, such as differential or Fourier transform operators. They are interested in learning more about this "framework" but have not come across a formal introduction to it. They ask if there is a specific course where this terminology and notation is introduced. The other speaker suggests that Fourier transforms are first covered in a differential equations course and are used in linear time signals analysis, which is the first course in the signal processing sequence for engineers. They also mention that a graduate course in functional analysis would be helpful in understanding these concepts. They recommend looking into books by Dr. Christian Constanda for more clarity on these subjects.
I am about to start a graduate program in signal processing. A lot of the literature that I've been recently browsing, uses the concept of operators on functions - such as a differential, or Fourier transform operator. I really like this "framework" (for lack of understanding) but have never seen a formal introduction to it - it just started appearing.

Is there a specific course where this terminology and notation is introduced?

Is there a specific course where this terminology and notation is introduced?

Um not quite clear, but are you asking where Fourier transforms first show up? Undergraduate engineers and math majors learn all about them. They're first covered in a differential equations course and engineers start using them (and laplace transforms and the ilk) in the linear time signals analysis I course, which is the first course in the signal processing sequence.

I think a graduate course in functional analysis is what you are looking for.

functional analysis, partial differential equations, and advanced differential equations will get u used to using Fourier transformation, differential operators and functionals.

my professor, Dr. Christian Constanda has written some incredible books for both PDE and ADE if u need books on these subjects search his name it doesn't get more clear than him!

Yep, functional analysis is what you're looking for.

1. What is the purpose of learning functions and operators in a science course?

Functions and operators are essential tools in many scientific fields, as they allow us to describe and manipulate mathematical relationships between variables. They are particularly important in subjects such as physics, chemistry, and engineering.

2. At what point in a science course are functions and operators typically introduced?

The specific timing may vary depending on the course and instructor, but functions and operators are usually introduced in the early stages of a science course, once students have a basic understanding of algebra and other mathematical concepts.

3. What are some common functions and operators students may encounter in a science course?

Some common functions and operators used in science include logarithmic, exponential, trigonometric, and differential operators. Different fields may use different functions and operators, but these are some of the most commonly encountered in scientific studies.

4. How can understanding functions and operators improve my understanding of scientific concepts?

Functions and operators allow us to express complex relationships between variables in a concise and precise manner. By learning how to use them effectively, you can better analyze and interpret data, make predictions, and solve problems in your scientific studies.

5. Are there any resources available to help me learn and understand functions and operators?

Yes, there are many resources available, including textbooks, online tutorials, and practice problems. Your instructor may also provide additional materials and resources to help you better understand functions and operators in the context of your specific science course.
