Friday math movie - Trigonometric Graphs
By Murray Bourne, 28 Dec 2007
This week's video gives an overview of the concepts behind trigonometric graphs and demonstrates some of the interactive Flash applets that I developed for the Trigonometric Graphs chapter in Interactive Mathematics.
Let me know what you think of my first YouTube movie...

Nice movie! The graphics are very nice. They make the trigonometry very accessible. Great job introducing the basic concepts.

My six-year-old liked the music "but not the math" π
I liked the math, though I might have liked it to be a little more explicit about how those circles generated those sin waves. It seemed to be somewhat implied that the students would already understand that connection.

Sol: Thanks for the comment!
Mathmom: Thanks for getting your 6-yr old's reactions, too!
Your comment about the circles is very valid. Perhaps I am relying too much on the 'picture is worth a thousand words' benefit.
The greatest reaction to that Flash applet comes from mathematically-competent adults. They say things like "wow - I never knew that's where sine curves come from".

Hey - cool video.
Some of the text goes a bit fast, but I like the movie as an introduction (and maybe for revision) of trigonometry graphs.
Are you doing some more videos?

Yes, Steven, another math music video is in production. Watch this space.

It is really fantastic.!!
I enjoyed very much.
I' show it to my students.

Hi Rosa and thanks for your kind comment. How did your students react?
Is there scope in your class for getting the students to make short movies about the mathematics they are studying?

Great site! It really helped.

Great Video. I'm going to show it to my trig class Tuesday as they review for their test on trig graphs! Thanks

Nice. Great graphics and music. How did you do the graphics. Where did you get the music. How did you do the timing to get the text to appear right on the beat? I have been wanting to do such videos for classes, but they seem to be a lot of work.
Cheers, Hans

Hi Hans
Almost all of the graphics come from my Interactive Mathematics site, including the animations (which were done on Flash).
The movie was edited in Camtasia Studio, which gives you the ability to synch the images with a visual indication of the sound, something like this (this is the very beginning of the soundtrack):
There are also products around that will synch the music and images automatically for you, like Muvee. This doesn't give you the precise level of control that I want, but it sure saves a lot of time!
Hope that helps.

Love it! Will use it with my class after we look at the unit circle. Watched it over and over. Liked it more and more.

Glad you enjoyed the video, Carlton.

Great movie! Will show it to my college trigonometry class.

What a gem! The fast music is invigorating - just what my students need for their "after lunch" Maths class.

@Joanne - glad you found it useful!

I loved your video, simply fantastic introduction. My students were fascinated by the music and also the animation. Is it possible to make it a little slower?

@Nita: One possibility for changing the speed is to choose the gear icon at the bottom right of the video (near where it says "YouTube") and choose "Speed". You can bump it down to 50%. Shame they don't have a 80% setting.

I really enjoyed the video, its both informative and upbeat. Thank you
