How do I express bc for PDE
http://www.mapleprimes.com/questions/220884-How-Do-I-Express-Bc-For-PDE?ref=Feed:MaplePrimes:Tagged With maple
<p>I have a PDE with boundary conditions, from a NASA paper. I always seem to have problems expressing the bc.</p>
<p>PDE := diff(u(x, t), t) = (1/4)*exp(2)*exp(-u(x, t))*(diff(diff(u(x, t), x), x))/(x^2+2);</p>
<p>The initial/boundary conditions are</p>
<p>@t=0, u(x, t) = 2-2*ln(-x^2+2)</p>
<p>@x=0, diff(u(x,t),x)=0 ## this is the bc I have problem expressing</p>
<p>@x=1, u(x,t) = 2+ln(1+t)</p>
<p>The exact solution given in the paper:</p>
<p>2 + ln(1+t) - 2*ln(2-x^2)</p>
<p>I tried</p>
<p>ics := u(x, 0) = 2*(1-ln(2-x^2));</p>
<p>bcs := D[1](u(0,t))=0, u(1,t)=2+ln(1+t);</p>
<p>PDEtools[Solve]([PDE,ics,bcs]); ## no solution</p>
<p>How do I do this?</p>

http://www.mapleprimes.com/questions/220863-Function-Coefficient-General?ref=Feed:MaplePrimes:Tagged With maple
<p>Hi all, i wan to write getCoeff() function get coefficient general.</p>
<p>Example</p>
<p><span style="font-family:courier new,courier,monospace;">f := a^2*b^2*c^2 + 2*a^2*b^2 + 2*a^2*c^2 + 2*b^2*c^2 + a^2 - 6*a*b - 6*a*c + b^2 - 6*b*c + c^2 + 8</span></p>
<p><span style="font-family:courier new,courier,monospace;">getCoeff(f,a^2*b^2*c^2) return 1.</span></p>
<p><span style="font-family:courier new,courier,monospace;">getCoeff(f,a^2*b^2) return 2.</span></p>
<p><span style="font-family:courier new,courier,monospace;">getCoeff(f,a*b) return -6.</span></p>
<p><span style="font-family:courier new,courier,monospace;">getCoeff(f,a^2) return 1, ...</span></p>
<p>and how to get coefficients freedom ?</p>
<p>Thank you very much.</p>
