Let R1=1,R2=2,R=3. Then dA/dr becomes 2π, 4π, 6π. But putting radii values in the formula A= πr^2; Area A1=π,A2=4π,A3=9π . The changes in Area wrt r ...π ,3π,5π etc. Both results are not maching.why?

Hi Tiago, great video very useful. Is there a way, instead of sum to list the values. E.g show how much John paid. so list £500, £400, £250 in a cell?

bro why couldn't you just do it in desmos basically I want to render polygons like cylinders and I want to have multiple points, each as part of an array with coordinates sin(index no x d),cos(index no x d) so that d=360/totally number of points we get a circle of total number of points
@tsvilissack19 күн бұрын
This proof uses the trigonometric identity for sine of sum of two angles. As far as I know the proof of that identity uses the rotation matrix properties, hence this is a circular proof.

Fyi you can do recursion in desmos so this writing of f(f(... Is a tad unnecessary.

You can also get rid of the vars a,b cause you don't need them to make for a dragable complex number. But I suppose you may want them to be able to change real and imaginary separately more easily, I guess...

What is going on: The 1st line takes point and somehow iterates it like the mandelbrot fractal (Z^2 + C) The 2nd line takes in a point and gets the distance to the origin The third line then gets all possible points on the plane and then after iterating them alot with the first function it tests if the final points are close to the origin to see if they converge or diverge after being iterated, then it shades all starting points that end up converging.

could you explain how does (x+iy)²=x²+y²? i tried to get it, but since i'm not deep into this kind of math, thought there could be some kinda rule that i'm not aware of
@mathematics.proofsАй бұрын
It's |x+iy|^2=x^2+y^2. It's because |x+iy|=sqrt(x^2+y^2). |x+iy| means the magnitude of the vector x real units across and y units upwards. Vectors have both a magnitude and direction.
@carminefiore8627Ай бұрын
maybe I wasn't clear enough. if you calculate |x+iy|², you get x²-y²+2ixy. my question was, how do you get x²+y² from x²-y²+2ixy? is there some rule in the study of the complex numbers, or is it simply manipulation on the expression?
