"For most of the thirty years since I was graduated from high school, I've held the concepts of Sines and Cosines at arms length. I knew that they were good for something, just as the odd wrench that you find at the bottom of the toolbox must fit something, but as to what, I was clueless.

An acquaintance suggested that I view the Project MATHEMATICS video collection on the subject. As a result, my teeth are whiter, my cat is friendlier, and my mileage has improved drastically. Okay, maybe not -- but I now know more about *why* people care about Sines, and how they might use them. I'm sure my knowledge is a pale reflection of reality, but I am pleased to have it, nevertheless. I owe it to the Project Mathematics videos, and I thank you for them."


"...I just wanted to send you a quick note of thanks for the elegant and captivating way you've managed to portray mathematics in your "Project MATHEMATICS!" videos.

I was an innocent bystander, just checking in to a Seattle hotel for a routine business trip, when I flipped on the TV to lull me as I've done hundreds of times before. This time though, as I idly scanned the channels, I landed on a station showing one of your videos, and the simple, engaging way it managed to explain trig was eye-opening. I'd forgotten much if not all of my high school and college trig, but I found myself sitting open-mouthed on the edge of my chair and devouring the whole thing. I couldn't take my eyes off the screen ...your video reminded me why I like learning for learning's sake.

Don't suppose you know of any similar series for physics, chemistry and/or biology do you? I'd rather watch your stuff and others of its ilk than a copy of "Armageddon" any day."


"...I'm an adult who has avoided mathematics most of my life because I never had teachers who explained what in the world was going on. I assumed I was just an idiot, but since I've worked at research facilities as a technical secretary and have seen the joy that mathematicians, engineers and physicists seem to get out of their equations, I wondered what they knew that I didn't know. Your program changed my perception!

I must admit that the classical music that's played on the program lured me into watching your video, and through sheer curiosity I couldn't believe that I was understanding, for the first time in my life, what the world of mathematics was all about. I just love the visual effects that explain what the equation is representing. My husband and I totally agree that we would have developed a definite interest for math a lot sooner if it had been explained to us in this manner.

I had to write to you and tell you how much your program has influenced my life and has actually sparked a wonderful interest in learning algebra, geometry, trig and calculus. The visual effects have opened a whole new world to me and I can finally pursue areas that require mathematical skill because I'm no longer afraid of "scary ol' math."

Thank you for changing my world!"


"...I am currently (as I have been for the last 21 years) teaching mathematics in Texas, just a hop, skip and jump from NASA. I have seen bits and pieces of the videos on our local NASA channel, but had not seen the lead in until one of our teachers, attending a workshop, secured a couple of them. I am so impressed. I really enjoyed them myself, and feel sure a number of my students and those of the other 14 math teachers could profit from the use of the videos in class. The voice over stated that there were workbooks available and if they are the same quality as the videos --well, what can I say?

Please send me the information regarding the videos that are available and any and all supporting materials, too. I am looking forward to hearing from you soon as "Sines and Cosines, Part III is my pre-calculus chapter 6 -- but waaay better."


"I am a computer engineering student at the University of Minnesota. I got home from the lab tonight and flipped on the TV before going to bed. I saw your math program dealing with trigonometry and the various trig identities for sin and cos. I would like to say two things. Your math videos have proved to me that done correctly, television can actually be a useful teaching method and that in the brief span that I watched I was actually able to find out why something works rather than just how.

This has always been important to me. Although as an engineer I am supposed to be this all-knowing math machine, there are many times when I finish a course and still don't really know why things work the way they do. Maybe because I am supposed to be a math genius this bothers me more than most people. I was educated in a very strict liberal arts environment and never had very much math in high school. I took trigonometry in college and am still taking math now. I'll be going into multi-variable calculus. Although I did well, I was always left feeling unfulfilled by not really knowing why these identities (which we had to memorize) were what they were. Your videos did an excellent job of illustrating why. It was wonderful to feel the great "A-HA!" experience again. I especially liked how the video progressed from the addition and subtraction formulas for sin and cos and was able to show how the double angle formulas and the fundamental identity sin2+cos2=1 can be derived from those. I thought that was pretty slick.

I was so impressed that I would like to purchase these videos. Please let me know how I can get copies. Thank you for your hard work and keep up the good job you guys are doing."


"...I stumbled upon a wonderful presentation on television today which turned out to be from your Project MATHEMATICS! As a high school math teacher, I was impressed by the animation used to present the concepts. I saw two topics today, one on 4th degree equations showing how changes in the equation resulted in changes in the graph, and another on the Pythagorean Theorem. The animation quickly and easily shows relationships in a way I cannot.

Based on the little bit I saw today, I can see a real use for them in the classroom."


"...I recently saw something on the Discovery Channel that was produced by Project Mathematics on Trigonometry. It was produced in 1992, and showed the relationship between trigonometry functions and angles of a triangle.

I was wondering if I could get more information about this series. I am a high school math teacher and will be teaching Algebra I and Algebra II/Trig. this year, and I thought that video would be wonderful to incorporate into my class."
