can maple match a equation structure regardless of variable name?

<p>if just expect to find whether equation is like</p>
<p>(a-b)*(c-d) + (e-f)*(g-h) = i</p>
<p>if use equal , it will care the variable name, is it possible treat the variable name as a wildcard to match the equation structure only </p>
<p>the structure i mean is *, +, -, =, ()</p>

<p>I have to do this problem:<br>
"Using interactive components, build an app that, recording the time at which a cyclist passes by an arbitrary number of steps, calculate the time required to complete the marathon. Remember that the length of the race is 42.195 kilometers."</p>
<p>I know the method: I use the command "Statistics:-LinearFit" for variables number of points (x=Space; Y=time), then i replace 42.195 to x of the equation of line and i find y(the time).</p>
<p>My problem is thath i don't know how can I make to choose the number of points whence I would get the equation of the line.<br>
I had thought to a Combo Box, but i don't know how does it work.</p>
<p>Thanks in advance<br>

<p>Hi all,</p>
<p>I have this equation that I can not get all solutions symbolically:</p>
<p>restart:</p>
<p>eq1 := cos(lambda*ln(r1))*cos(lambda*ln(r2))+sin(lambda*ln(r1))*sin(lambda*ln(r2))-1 = 0:</p>
<p>solve(eq1, lambda, allsolutions) assuming r1>0, r2>0, r2>r1</p>
<p>when r1:=1: r2:=2: I get the solution</p>
<p>2*Pi*Z/ln(2)</p>
<p>when r1:=1.1: and r2:=2.1: # no solutions</p>
<p>How to get symbolique solution</p>
<p>Thanks</p>
<p> </p>

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>
