  I don&apos;t know why, but I love that weird sound they make when they fast-motion her writing on the board.

  My favorite parts are when she finishes a new section and when she’s done looks at the camera like “I know, I know.” 😂😂 but really this helps A LOT and helps me look at it more clearly. I have a learning disability and when something is very busy I get overwhelmed so to be able to chop it up like this and make sense of it means everything to me.

  I’ve been severely struggling with the trig portion of calculus for a while. I narrowly survived trig because my professor didn’t really make sense to me. I’m not kidding when I say this saved my whole academic career. THANK YOU!!!!

  You just taught me what my trig teacher utterly failed to. Thank you.

  Hi Nancy, hope you are well. &nbsp;I wrote on another video of yours a few weeks ago. &nbsp;I am currently doing engineering as a mature student and have not done maths in a long time and finding your videos very helpful. &nbsp;Thanks for being patient and setting a calm teaching mood where the information flows very easily. &nbsp;This technique or style of yours &nbsp;is the right way to teach. &nbsp;There is often so much angst in learning and the teacher adds to the chaos of it by their personality I think. &nbsp;The end result, is confusion and lack of transfer or knowledge as I am finding from my online uni lectures which are often presented by &apos;junior&apos; Phds who have no idea of how to teach. &nbsp;It is almost like, hey this is what we know and we are so great - aren&apos;t we? &nbsp;Can you be so great as us? &nbsp;This is the kind of the message I get. &nbsp;Hardly any effective transfer of knowledge. &nbsp;Text books are written like that too, just a representation of the writer&apos;s ego, particularly how formulas are written with flamboyant text - which just adds to the fear of what is possibly a simple formula. &nbsp;So a big thank you for who you are and how you do this. &nbsp;Please keep up the good work and I think there will always be a need for these videos and this teaching style. &nbsp;You remove the fear of maths which is, I think the biggest hinderance to many people learning the subject. &nbsp;I have seen in my life that often something learned in fear is forgotten easily as your mind tries to heal up the trauma of it - the opposite in some circumstances is also true where you cant forget a bad experience but I think generally, if something is taught in a relaxed, everyday kind of way, it stays in your mind longer (it does for me anyway). The maths teacher has always been the feared one for me (and for others I have felt, from watching and talking to other students in the past who have been in class with me particularly when I was in high school many years ago. &nbsp;Most people have a mini panic attack before their maths exam - not so in other subjects I thought. &nbsp;I think this stems from historical teaching techniques over generations). &nbsp;I feel there are so many great minds out there which have not been taught properly and the end result are mediocre careers and lives. So, God bless you and thank you for what you are doing for humanity (you probably haven&apos;t though of it in that way but you are helping many I think with your teaching). &nbsp;Have a great day!!!

  Couple things that I observed which helped me remember this: (Cos, Sin) — remember CS for computer science. Also, 1 == Sqrt(1), which makes the pattern even more obvious. Also 2 == Sqrt(4), so the pattern is actually quite nice if you look at it this way. Thanks so much Nancy, awesome vid.

  Her expression at <a href="https://www.youtube.com/watch?v=c819bGfH8FA&amp;t=216">3:36</a>-<a href="https://www.youtube.com/watch?v=c819bGfH8FA&amp;t=217">3:37</a> says it all about how she knows most people don&apos;t understand jack.
