Generating Conic Sections with Circles | Part 2. The Parabola
zhlédnutí 26KPřed 3 lety
Strengthen your problem-solving skills at: brilliant.org/ThinkTwice Let C be a circle centered at F and let L denote a line on the same plane as C which doesn't intersect C. Then construct a variable circle tangent to L and C and denote its center as X. A collection of all such possible centers X is a parabola.

    Are there any other examples of this where the sum of powers, is equal to another power of sums? I.e. where the 1^a + 2^a + 3^a + ... + n^a = (1 + 2 + 3 + ... + n)^b?

    A great way to explain it by cutting the strips and then twisting them, thanks. I have one for you. If the formula for the surface area of a circle is πr2, should the volume of a sphere be πr3? I would love to see a visual explanation of that.

    for the quadrilaterall, let A,B,C,D in order be the points of the quadrilateral and x the candidate for the "fermat" point. we want to minimize |x-A|+|x-B|+|x-C|+|x-D|. We take the gradient with respect to x and get (x-A)/|x-A|+....+(x-D)/|x-D|=0 for the minimum (assuming it exists). So let a,b,c,d be the vectors that are in the same direction as x-A,...,x-D but with unit length. This means we want a+b+c+d=0, since vector adition is tip to tail this means that we have a quadrilateral with lengths of the same size, ergo they consititue a rombus ergo it is a parallelopiped, so a+c=0, b+d=0. This means that x is between A and C as well as B and D. Meaninf that x is the intersection of AC and BD.

    Question, how do we know that every polygon has at least one convex vertex ( I assume that is a vertex that has an angle < 180 with its neighbouring sides?) in the first place, so that the diagonal algorithm can work?

  • @danielpalecek4090
    @danielpalecek4090 Před 5 měsíci

    dragon curve is copied on one end and rotated 90°, julia set is complex square rooted, which is halved angles on one point and copied 180° around it and square rooted distances. dragon curve kinda looks like julia sets. I'll try make a mandelbrot set for dragon curves and see if it's fractal or something boring like circle. the most obvious way of doing it with moving the point of copy and rotate is circle.
