AI Thread Summary
Several websites can help find the roots of a fourth-order polynomial when provided with its coefficients. The quartic formula, established in the 1500s, is essential for solving these equations, and resources like PlanetMath and Wolfram Alpha are recommended for assistance. For practical use, calculators like the TI-86 can quickly approximate the roots. However, the quartic formula can be complex and cumbersome, making it less practical for manual calculations. Utilizing online tools or calculators is the most efficient approach for obtaining instant results.

Is there a website that given the coefficients of a order 4 polynom, it will give me all 4 roots of this polynom?

Thanks.

you are looking for the quartic formula, discovered in the 1500s. surely it is out there, perhaps on wolfram.
 
here you go:

Well, if you want to use a calculator, like the TI-86, it will find an approximation of the roots fast...Maybe that is what you mean.

As for the entry given on PlanetMath.Org, I note at the bottom of that page the "disclaimer": The formulas for the roots are much too unwieldy to be used for solving quartic equations by radicals, even with the help of a computer.

Thread 'Video on imaginary numbers and some queries'

Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
