I'm doing a calculation in PHP using bcmath, and need to raise e by a fractional exponent. Unfortunately, bcpow() only accepts integer exponents. The exponent i
Example given in JavaScript: Suppose we have two arrays [0,0,0] and [1,1,1]. What's the algorithm to produce all possible ways these two arrays can be combine.
I think most people know how to do numerical derivation in computer programming, (as limit --> 0; read: "as the limit approaches zero"). //example code for d
As we can see int has 4 byte in memory, that are 32bits, after applying range formula , we can see range of int -2147483648 to 2147483647. I have calculated the
I want to make a spiral galaxy in Unity 3D using C# ( i use a derived logarithmic spiral ). I want to set the end of the arms less dense than the middle, but mi
I have made a functioning (if possibly extremely verbose) game of rock/paper/scissors. If I run the game by calling the function once over and over the 'compute
Is there any way to get the step-by-step solution in SymPy? For example: x**2-5 = 4 step 1 x**2-5+5=4+5 step 2 : x**2=9 step 3 :x = 3 or x= -3
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
