how can i construct the bezier curve if i only have points in x axis?can i do this act or need points for x and y axes related to t parameter? i want constructe a bezier curve(from degree N)in a given interval and known point in that interval(that are random), but i have points only in x axes!!Whether this is feasible? ...
Hello, This is an odd one I'm puzzled about. I recently noticed at the Gnu Octave prompt, it's possible to enter in negative zeroes, like so: octave:2> abomination = -0 And it remembers it, too: octave:3> abomination abomination = -0 In the interest of sanity, negative zero does equal regular zero. But I also noticed that the si...
I would like to take surveys (2 or more choices), and place the results in a table. I just want to know how I would tally up the results in a sql query. Even more, should i be doing the math within the query, or just use PHP to do the math? Example Questions Table question_id (int) question (text) answer_1 (varchar) answer_2 (varchar...
This question is based on a previous similar question. I have the following equation and an adjusted (some random data): 0.44*sin(N* 2*PI/30) I am trying to use the FFT to get the frequency from the data generated. However the frequency ends up being close but not equal to the frequency (which makes the wave a bit larger than intended)...

Hi! If this is OT, please tell me where to repost it. I need to render some math equations, in real time. Where can I find a mapping of the LaTeX "english" names (like \sum ) to symbol XYZ of ABC.ttf ? I can read + render ttf's fine; I just don't know where to get the ttfs that have the math symbols and how they're indexed. Thanks! ...

i'm trying to do factor analysis for a co-occurrence matrix(C) , which is computed from the term-document matrix(TD) as follows: C=TD*TD' In theory C should be positive semi-definite , but it isn't and the factor analysis algorithm can't work with it because of this.I can't change the algo because of speed reasons). I look it up and ...

How many permutations of the androids dot login system are possible? I know for a fact the solution to this lies in Discrete Math, specifically Permutations Without Repetition, If your answer doesn't use permutations or combinations you are incorrect. The length of passwords is between 4 and 9 dots, There are a total of 9 dots to p...
in my program, i think my count variable is not holding the value.. what do i do so that it can hold? here`s my code. static void Main(string[] args) { double a; double count = 0; Console.WriteLine("Enter the Numbers : "); for (double i = 1; i <= 10; i++) { a = Convert.ToDouble(Con...
i would like to calculate the distance between two x/y coordinates. This calculation itself isn't that difficult, however I need the corners and sides of the grid to be 'connected'. This means on a grid of 500x500 that the point after 499 becomes 0 again. The distance between e.g. 0,0 and 0,495 should be 5 then. Is there any good mathe...
Back to the basics... For reference types, one can do this: SomeType someObject = firstObject as SomeType; if (someObject == null) { // Handle the situation gracefully } else { // Do stuff } For value types, my understanding is that we have implicit conve...
Making a simple app for my android. in my xml interface there is a text box in which the user will input a number (for example: 10). the id of this text box is "input1" how do I call the value of input1 in java and then perform a calculation on it? For example... suppose input1 = x x + 5 or x*2 and for that matter, how do I have...

I have an math problem in Isometric projection. I have reading an article: Axonometric projections - a technical overview. For the Isometric projection part, it give an mathematical formula for conversion 3D point into 2D point for the x part the formula is: x' = ( x − z ) cos(30); But i also check for wiki for Isometric Projection s...
