I have used a formula to create an X and Y coordinate that I would like to create a point from. They are held in the attribute table, and I don't know how to us
I need to attain the slope of a linear regression similar to the way the Excel function in the below link is implemented: http://office.microsoft.com/en-gb/ex
I have created some very basic implementations of the mentioned models. However, although graphs seem to look right, the numbers don't add up to a constant. Tha
So I am trying to develop a formula that will sum all odd Fibonacci numbers up to and including a given number. For example: Given number is 4. Then result sh
I have a list of numbers a1, a2, a3, a4, a5, ... and so on. If we find XOR of all subsets then I noticed that frequency of each distinct XOR is the same. Exam
I want to find out the clockwise angle between 2 vectors(2D, 3D). The clasic way with the dot product gives me the inner angle(0-180 degrees) and I need to us
I have a function in my program which rotates a point (x_p, y_p, z_p) around another point (x_m, y_m, z_m) by the angles w_nx and w_ny. The new coordinates are
How can I get the current quarter we are in with javascript? I am trying to detect what quarter we are currently in, e.g. 2. EDIT And how can I count the numbe
I need to find a point where a line (its origin is ellipse' center) intersects an ellipse in 2D... I can easily find a point on a circle, because I know an angl
I'm attempting to make a iPhone flow rate calculator that uses these 3 formulas. Pressure ratio b b = p2 + 0.1 / p1 + 0.1 The C-value and B-Value are given
I'm confused about the following integer math in python: -7/3 = -3 since (-3)*3 = -9 < -7. I understand. 7/-3 = -3 I don't get how this is defined. (-3)*(-
We are using MySQL and developing an application where we'd like the ID sequence not to be publicly visible... the IDs are hardly top secret and there is no sig
I have multiple estimates for a transformation matrix, from mapping two point clouds to each other via ICP (Iterative Closest Point). How can I generate the av
How can I find the line of intersection between two planes? I know the mathematics idea, and I did the cross product between the the planes normal vectors bu
I am trying to solve and display a graph of the following equation: f'=af²-bf Therefore I have tried to use scipy.integrate.odeint library function to so
I need an efficent algorithm to do math::power function between two floats, do you have any idea how to do this, (i need the algorithm not to use the function
I want to round up double to int. Eg, double a=0.4, b=0.5; I want to change them both to integer. so that int aa=0, bb=1; aa is from a and bb is from b
Have I missed a standard API call that removes trailing insignificant zeros from a number? var x = 1.234000; // to become 1.234 var y = 1.234001; // stays 1.234
I am making generated shapes in a fragment shader and part of it involves drawing the border between objects ie the dividing line between them. Currently I have
