GBK Programming 1

In today's plan, we focus on essential programming concepts with DrRacket. Key activities include reviewing the syllabus, submitting an introductory email, and preparing for tomorrow's mini-quiz on expressions. We'll explore the Definitions area in DrRacket, learn about creating expressions through examples like (define x 8), and understand how to use the Help Desk for function assistance. Lastly, remember to log out and clean up before leaving.
