The Math Lab’s last day this term will be Monday, December 14. We will be closed December 15 through January 10.
In the spring term, our hours will be:
- Monday and Wednesday, 9:30 am to 9 pm;
- Tuesday and Thursday, 10:30 am to 9 pm; and
- Friday, 9 am to 1 pm
Enjoy the holidays. See you January 11.
Once you’ve mastered the unit circle, how do you extend your knowledge to trig functions over many cycles?
The unit circle looks like this:
The numbers around the circle represent angles, measured in radians. The angle variable is called theta.
How can you represent that angle on a coordinate plane? Imagine that you break the unit circle open at theta = 0, open it, and straighten it into a line.
That line is an x-axis. Add a y-axis and you have a coordinate plane set up to graph trig functions.
Thanks to Asma Stanikzai, a student in MTH167, for this idea.
NOVA Manassas professor Matthew Westerhoff is working on a project, Doctrina, described in today’s Daily Flyer. Doctrina will be a series of videos in various math topics. Prof. Westerhoff already has some videos for the project posted on YouTube, mostly in Calculus II topics: volume integration, series.

Here is a proof that 2 = 1.
Is there an error in the proof, or does 2 = 1? What do you think? Please reply by October 29 with any thoughts you wish to share. I’ll weigh in after that.
