    You probably know this, but you can change desmos graphs into degrees instead of radians. Just click the settings tab in the top right corner. Looks like a wrench. Love the videos btw!

    I adore learning about these fun math problems. Showing graphs and math as something less abstract (based on simple principles) helps tremendously in understanding them. From part 1 equations slowly grow more complex but you did amazing job at showing the stages and reason behind them eliminating any confusion.

    Love the video, this sort of stuff is exactly what I used to think about in my math classes, just trying to rotate a graph because I feel like it’s possible, and trying different things out to see if I can.
    I know the ‘t’ equations aren’t suitable for animating the graph in the way you were trying to show, but I didn’t think they were any less interesting than when you don’t use it to draw the graph, it’s just a different way to animate the graph by changing the lines themselves. If you could calculate the right coefficients for t then I’m sure you could use it in some interesting ways. I already thought the ones you showed were quite cool-looking, but again, it didn’t preserve the original shape of the graphs, so I understand why you didn’t continue to use them. To me it’s just a different ‘dimension’ or ‘medium’ in which you can animate them.

    Thanks to part 1 of this series i was finally able to find the reason why the graph x^2 - y^2 = 2 is the same as 1/x rotated clock-wise by 45 degrees
    You literally just rotate 1/x by 1/4pi and you indeed get x^2 - y^2 = 2

    At 5:30, the equations are applying the transformations incorrectly. They should be:
    (x, y) : start
    (x + a, y + b) : move the graph away from (a, b)
    (xcos(θ) - ysin(θ) + a, xsin(θ) + ycos(θ) + b) : rotate about the origin
    ((x - a)cos(θ) - (y - b)sin(θ) + a, (x - a)sin(θ) + (y - b)cos(θ) + b) : move back towards (a, b)
    On a related note, if you want the windmill at 7:02 to keep its shape, you should be using:
    (x - cos(θ))sin(θ + L) + (y - sin(θ))cos(θ + L) + 0.37 = 1/5 sin(5((x - cos(θ))cos(θ + L) - (y - sin(θ))sin(θ + L) + 2.64))
    Or better yet, to rotate it at a different speed than it orbits the origin:
    (x - cos(θ))sin(3θ + L) + (y - sin(θ))cos(3θ + L) + 0.37 = 1/5 sin(5((x - cos(θ))cos(3θ + L) - (y - sin(θ))sin(3θ + L) + 2.64))

  • @jacobcowan3599
    @jacobcowan3599 Рік тому +2

    I'm unsure if someone's already said this, but you can make your list even easier!
    By setting a variable a=10, for example, you can then create a sequence n=[0...a-1] that will automatically fill in the integers in between. Then you can say L=pi*n/a and it will make L exactly the same as shown in your video, except with less typing. Plus, you can modify the number of copies with a slider or animation!

    • @warioseggs

      or you could use the variable of a to make a list of the radians with the 0 to a list by using “for i” making it become
