### Plot implicit equation in sub-quadratic time complexity

It is fairly straightforward to plot an explicit equation such as $y=x^3+3x^2+2x+5$ in linear time, because you can just iterate through all $x$ in your graphing space and use the equation to ...

### Why does this algorithm to plot implicit equations work?

This may be an obvious question, but I can't seem to figure it out. I found an algorithm that receives an equation, and in order to plot its graph, for each pixel in the screen, it will replace the ...

### How do computers draw function graphs?

Could anyone give me a general overview of the algorithm computers use to draw graphs? I'm guessing it is either by graphing many, many points and just connecting them or by doing a general study of ...

### Given two overlapping datasets (think Venn Diagram), what is the point/plane called that separates the middle from either side?

Or, if you prefer a typed out version: Given the following two datasets: [Category A]: 1,3,4,7,8,9,13 ... 28,30 [Category B]: 29,32,33,37 ... 61,62,63 Plotted ...

### Algorithm to find the rotational degrees of a point according to some function

Hi I'm developing a game. In this game you can fire a missile, the path of the missile is given accord some function. For example if the function is f(x)=x^2 the missile should look like this. Is ...

### 2D Eculidian matrix to 2D cartesian graph/plan

Can anyone help ? I am trying to convert a 2D matrix of distances to a 2D graph. For instance, I would like to go from this : ...

### Is there a general algorithm that can be implemented via a computer program that can identify the function being represented by a graph?

It might help understanding my question to think of the hypothetical situation in which I draw a seemingly random function on a piece of paper (with an accurate coordinate axis already on the paper), ...

### 1/f “Pink Noise” for the Math-Disabled

I have very little skill when it comes to math beyond all the elementary level operations (addition, subtraction, multiplication, division, mean, mode, etc) and a vague grasp of statistics, what a ...

### Needs alternative algorithm for a graph problem

There is a network of connected electric bulbs each with a unique id. Each bulb has a switch. When the switch is clicked, the colour of the bulb changes and also the colours of connected bulbs change. ...

### Graph for time rating (A bit like $x^3$)

I am developing a webpage where you can post questions, and other people can rate them. And the front page should have a list that is selected based on an algorithm that takes into account the time ...

### Algorithm to find the total resistance between 2 vertices of a graph

Assume we have a graph, and resistors are placed on the edges. I want to know if there is an algorithm that find the total resistance between any 2 vertex. i have a hard time finding any description ...

### How relevant is an inverted x-axis on a cartesian chart?

I'm a developer and some fellows here asked me if I could reverse x-axis on cartesian charts. Since this functionnality is not natively supported by the components I use, I wonder how relevant a chart ...
I have an equation like $$(x - a)^2 + (y - b)^2 = r^2$$ that represents a circle. I need to "plot" it very basically with a programming language. Computer graphics coordinate generally use the ...
