Week 3: 3 February

Here's the link to the Endnote cloud-based reference database and management program.
Do steps 1 and 2
.

Monday: Worked on finishing the response time modeling.

Wednesday: Discussed report writing, using Endnote Online for reference management, figure preparation, equations, and report structure.

Friday of last week: Here's the spreadsheet we worked on for using the solver to obtain the photoresistor response time.
We will use it as an example of how to prepare report/publication format graphs.

We will finish part 2 of homework 4, and begin part 3.
