    Undergrad Finding a transformation between two matrices

    How do we go about finding the transformation that was used to go from one matrix to another ( provided of course that the two are linked by a transformation) in general if all we have is two matrices.

    Graduate Factoring Method: Learn How to Use It

    you write: 5^2 + 4.13 =77 that's wrong. 5^2 + 4.13 =25+4.13 =29.13 same thing with your equations 1 and 2. How can 77 be equal to 8^2 + 1.13 ? and what exactly do you mean by ... in equation 1 and 2?

    Undergrad Existence of a function for the n-th prime

    has not been found does not necessarily mean does not exist. I suggest you try to come up with a formula and see what kind of problem you run into.

    Graduate New idea about Integer Factorization

    In fact it is not wrong. I will not offer a proof ( simply because it's really simple ) but I would say that the Fermat method has been around for more than 200 years and was studied by many very good mathematicians. Finding a "major" mistake this late in the game in the Fermat Method is...

    Graduate New idea about Integer Factorization

    Kadhir, what people want to see is simple: take a big enough number ( 50 digits say to start with) and use your method to factorize it in less time than with previous methods. If you do that, people will listen to you.

    Undergrad Evaluate this algebraic expression f(a,b)

    Thank you very much. I really did not know that we could use the Wolfram site.

    Undergrad Evaluate this algebraic expression f(a,b)

    I do not have access to the math calculators. Δ = 162*(a-b)*(a^2-b^2)*(a^3-b^3) -108*(a^3-b^3)*(a-b)^3 + 81*(a-b)^2*(a^2-b^2)^2 - 108*(a^2-b^2)^3 - 27*(a^3-b^3)^2 thanks

    Graduate Proving Integer Solutions for x^3 + y^3 = z^3

    So why am I not getting any feedback? 1: first about the idea itself, that we can in fact transform the original Fermat equation into a cubic equation 2: that it is just a matter of doing the algebra to prove it. if 1: is wrong, there is no point in considering point 2: And something I...

    Graduate Proving Integer Solutions for x^3 + y^3 = z^3

    we know the equation above does not have integer solutions ( Fermat last theorem having been proven few years back ). I am wondering if the following is a new way to prove that. let y = x +α and z = x + β now by simple substitution we get the following cubic equation: x^3 + 3(α-β)x^2 +...

    can you please show how you derived the 2-D formula. I am working with a similar problem where I know both formulas but cannot combine them into two. Thanks

    Undergrad Horner's Method vs (x-1)^n: Which is More Accurate for Evaluating Polynomials?

    "Could you please explain a little bit more on how numerical errors accumulate for (x-1)^4 when is x is about 1?" I took the numerical analysis course a long time ago. I am not sure I can provide you with an explanation. It has to do with substracting numbers that are almost equal...
