Can Maple find a determinant corresponding to a symbolic equation?
http://www.mapleprimes.com/questions/220242-Can-Maple-Find-A-Determinant-Corresponding?ref=Feed:MaplePrimes:Tagged With equation
<p>For exaqmple, the quadratic equation w^2 + uw + v = 0 corresponds to the deter minant</p>
<p><br>
| -u 1 1 |</p>
<p>| v 0 1 | = 0</p>
<p>|w^2 w w-1|</p>
<p>Is there any way to find a determinant corresponding to an equation, as above?</p>
<p>This is an issue in the preparation of a nomograph for the initial equation. </p>
<p>It is generally solved by trial and error.</p>

http://www.mapleprimes.com/questions/216348-Surd-Produces-Absurd-Result?ref=Feed:MaplePrimes:Tagged With equation
<p>I am trying to solve an equation using surd and I get a strange result.</p>
<p><img src="https://i.imgur.com/jX4592R.png" alt="" width="553" height="207"></p>
<p>solve(surd(x^4,8)=-2)<br> 4, -4, 4 I, -4 I</p>
<p>These solutions are clearly wrong.</p>
<p>The equation (x^4)^(1/8) = -2 has no solution.</p>
<p>This problem is equivalent to asking the computer to solve sqrt(x) = -2</p>
<p>which has no solution in R or C.</p>
<p> </p>
<p>However if I type</p>
<p>solve((x^4)^(1/8) = -2) , then I get no answer, which is what I expected.</p>
<p>Why does surd behave in this unexpected way.</p>
<p> </p>
<p>Also another thing I am wondering, why doesn't Maple simplify (x^4)^(1/8) to x^(1/2).</p>
<p>I tried the simplify command it didn't work.</p>

<p>It is very important that you learn to pose and solve equations in practical problems. Ernest Mach, a famous scientist of the nineteenth century, said that algebra is characterized by a lightening of mind, because the solution of a problem, after building the equation, you can "forget" all the practical situation to focus on the mathematical expression; everything that is not necessary to solve the problem no longer interfere with your mind. Another famous scientist, Isaac Newton, wrote that the language of algebra is the equation. To see a problem concerning abstract relations of numbers or amounts, simply translate the problem of colloquial language to the algebraic language. Here I leave the application for first order equations developed in 2016 Maple.</p>
