      Hey, sorry to inconvenience you, but could you lend a hand? OKX wallet has my USDT TRX20 and recovery phrase [ clean party soccer advance audit clean evil finish tonight involve whip action ]. How do I send it to Bybit or OKX?

    Beautiful visuals and explanation, but does the second variable "h" have to be equivalent to the first variable "h"? or does it not matter because you're simply using it to relate the "sin B divided by B" ratio to its counterparts for A and C?

    • @MathVisualProofs
      @MathVisualProofs  4 หลายเดือนก่อน +5

      Those are different “h” values. I should maybe have used a different letter for the second case to be more clear. But you are right that the name doesn’t matter as that value is used as an intermediate value to get the desired ratio equality.

    Great one. Thanks so much. Just wondering, how is Sin (180 - A) = Sin A ? at @2:15

    • @MathVisualProofs
      @MathVisualProofs  ปีที่แล้ว +9

      The sine measures the y-coordinate on the unit circle after rotating angle A. If you rotate 180-A you end up on the same half plane so the y-coordinate is the same as that if rotating angle A.

    Surely you are aware of the proof which goes via constructing the circumcircle.
    Also, a suggestion, please consider delivering a full course in Euclidean geometry. Would be great for high school students.

    • @MathVisualProofs
      @MathVisualProofs  ปีที่แล้ว +2

      Yes! I’ve seen that one. Sometime I’ll try to get around to it. Full course in Euclidean geo would be nice but would take quite a bit of time I think. Thanks for the suggestion.

    This is amazing! My teacher used a different visual proof to prove the law of sines but it was extremely confusing and hard to follow. This proof is so much easier! Are you going to make one for the law of cosines and the law of tangents?

      Yes, was interesting that they could prove PT with just this fact (as it is one of the trig facts that is not equivalent to PT).

    Not a 'visual proof' at all. It's just the standard high school level proof using geometry and algebra. A visual proof doesn't use any algebra, just figures and pictures.
