Dennis, your approach of teaching not just trig concepts but in general, demonstrate a logic found in true gentlemen and scholars. You're a gem and your efforts and selfless contributions are deeply appreciated. Kudos to you, kind sir.

I have watched all your videos in this series now, some of them several times. I am very impressed. Very few math videos on KZread match the caliber of yours. You can be very proud! Excellent, excellent job! I learned a lot. Thank you, ever so much!

Thank you very much, Cabin, for your viewership!

I cannot overstate how grateful I am for you taking the time to create this series of videos, you are an exceptional gifted and pragmatic teacher and have allowed me to gain a deeper understanding of a clearly complex subject. I look forward to further content especially if the subjects of calculus and geometry are given the same extensive treatment.

If you notice that x-coordinate of the point where the curve meets the midline is simply the x-coordinate of the maximum value minus 1/4 of the period, it is easily calculated: 0.996- (1/4)(0.996-(-1.860) = 0.996 - (1/4)(2.856) = 0.282 PS the x and y coordinates are backward. The point should be (0.282, -1.5)

The best trig teaching I have seen on You Tube - outstanding!

thank you for all these video. You have very less views, but the people who see your videos are the one's who actually want to learn and not just someone trying to pass an exams. A big salute to you, probably this is the best way trignometry could be taught.

Hi Dennis Davis. Thank you for taking me through the Trigonometry concepts nicely. I completed all the videos from TR-00 to TR-44. Now my journey with you for Trigonometry has ended. I really enjoyed the journey with you. Thank you once again for the enormous effort.

You are most welcome and thank you for watching! This trigonometry series is not quite finished, I still need to cover polar coordinates and equations. But I am slowing down as I reach the finish line. It has been a lot of work!

Love your content. It's like 3B1B but for students.

Thank you! Please don't let Grant Sanderson at 3B1B hear you say that or he may be insulted! Your comment is very nice, thanks.

​@@DennisDavisEdu He is absolutely correct your videos are just like 3B1B, Thanks for these.

Thank you so much for this! I'm in awe every time I see your videos. It's just so well structured/organized/presented. It's beautiful to say the least. How far is the finish line from here? any estimates will be much appreciated. Again, thank you!

Thank you for your nice comment, monke. I think I'll do polar coordinates and polar equations and then stop. Complex numbers are often introduced in trig courses but I think I'll leave that to a separate long-form video. I've been working on this course for about 3 years and I am getting quite tired (and slow) as I approach the finish line.

at 4:47, I thing that compressing the red line "Y" should also change the y express by adding a 2 => Y = sin2θ

shouldn't it be 0.282 first and -1.5 second in the parenthesis? 9:26
