You're astonishingly clear and neat, knowledgeable and consistent in academic excellence. Thank you for such an incredible effort in making the world a tempting place to learn and develop.

Sir I want to give you a noble prize for no reason. srs well deserved.

Sir, you are literally the best playlister on youtube when it comes to complete math and physics lectures.
I don't think anyone can fail trig after watching these from the beginning

Way better than how my teacher taught me. Thanks so much!

So, unit circle is used for only when K=1....???

Professor, why are there certain jumps in the playslists? For example, there is a playlist called physics 3.1 but then it jumps to 3.5. There are other playlists like this. Are we missing 3.2, 3.3 and 3.4?

When k = 2 add 45 degree or pie/4 for each section and if k= 3 add 30 or pie/6 for each section and if k=1/2 add 180 or pie for each section.


Hope I'm not wrong.

I wish I found your channel before I wasted all that time torturing myself with Khan academy.
