Try to solve a quartic equation
|
| |
I am trying to learn how to solve a quartic equation. In "Summary of Ferrari's method" of page [link] a root in the most simple case is x = -B/4/A + sqrt((-alfa + sqrt(alfa^2 - 4*gama))/2) My question is how to know the express inside sqrt is not negative: how to know... more »

Solution space of sum atan(x_k)<a ?
|
| |
Hello, Consider the problem: sum_k arctan(x_k) < a where k=1,...n and x_k are real variables and "a" is a given constant. You choose a specific choice of values for x_1,...x_n and give it to me. I should give you one of these two answers: "your choice satsfies the inequality" or "I don't know". Of course, I would like to avoid... more »

The old money-spinner: [link] "More than a dozen ground-based Dark Energy projects are proposed or under way, and at least four space-based missions, each of the order of a billion dollars, are at the design concept stage." The new money-spinner (in Einsteiniana's schizophrenic world it can... more »

Quartic equation
|
| |
Hi, I am trying to learn how to solve a quartic equation. In page [link] I found the "Summary of Ferrari's method" part looks easier for me but still have two difficulties: 1. Do you think I can solve a general quartic equation by only following this part and ignoring all the other parts?... more »

JSH: My Twin Prime Peak Gap equation used by Dentists world wide
|
| |
One of the weirdest gyps in math history is the idea of "research" around prime gaps, which is a lucrative scam for people who get government grants for "research" around it! Consider the prime 101. You may already know that it is a twin prime with 103 the other prime, but guess what? Even if you didn't you... more »

Expanding circle and its radii
|
| |
If you enlarge a circle or any round higher dimensional form you must extend the old radii and add new; just as long; radii inbetween the old. There are new radii inbewteen by sizes of infinity for an expanding round form. Mitch Raemsch
