Task Write a program or function that will determine if a point in 3D space lies on a 2D parabolic curve. Input 3 points in 3D space vertex of a 2D parabolic curve arbitrary point on the curve arbitrary point in space Input may be taken in any form (string, array, etc.) provided no other...

A couple years back we ran an advertising campaign using community ads on other network sites. For those who might be unaware, community ads are "community-vetted ads that that will show up ... in the right sidebar" of the respective site. You can see community ad threads on several graduated si...

Use Simpson's Rule Simpson's rule is a fairly simple method for approximating a definite integral of one variable. The idea is to approximate the function to be integrated by a series of interpolated parabolas, and then find the area under those. As I learned in first-year calculus, the form of...

What counts as a viable and usable programming language has been a subject of debate recently. One thing I've realized that our policy on this matter is rather fractured, with several different points covered in many different threads. Here are some examples: Our current policy on what counts...

Challenge Find an expression, at most 100 bytes long, with the longest type signature. Rules Any statically typed language with type inference is allowed The type must be non-ambiguous, but otherwise may include types without defined instances. For example Num [a] and Eq [a] are allowed, even...

Pentagonal numbers are generated by the formula, Pn=n(3n−1)/2. The first ten pentagonal numbers are: 1, 5, 12, 22, 35, 51, 70, 92, 117, 145, ... It can be seen that P4 + P7 = 22 + 70 = 92 = P8. However, their difference, 70 − 22 = 48, is not pentagonal. Output the pair of pentagonal numbers, P...
