Issues with integrating exp and trigs
https://www.mapleprimes.com/posts/208470-Issues-With-Integrating-Exp-And-Trigs?ref=Feed:MaplePrimes:Version Maple 2016
<p>There seems to be a bug with indefinite integration:</p>
<div style="background:#eee;border:1px solid #ccc;padding:5px 10px;">integrate(cos(t)*exp(-x*t),t=-infinity..infinity)</div>
<p>gives</p>
<div style="background:#eee;border:1px solid #ccc;padding:5px 10px;">0</div>
<p>Substituting any number for x, or assuming x >= 0 (or x<=0) does give the correct result,</p>
<div style="background:#eee;border:1px solid #ccc;padding:5px 10px;"></div>
<p>The problem also persists when assuming x>-1 (or x>-Maple_floats(MIN_FLOAT))</p>

https://www.mapleprimes.com/questions/222518-Specify-Color-For-Output-Variables?ref=Feed:MaplePrimes:Version Maple 2016
<p>Is there a way to specify different colors for different output variables? For example, if <em>x</em>,<em>y</em>, and <em>z</em> appear in the entire document as variables, I want <em>x</em> to be red, <em>y</em> to be blue, and <em>z</em> to be green whenever an output is displayed.</p>
<p>Thanks</p>

<p>
<p>will give me</p>
<p>
<p>which is not a solution of the PDE2</p>
<p>However, both differential equations are equal, only the arguments are swapped around. Am I doing something wrong, or is this a bug?</p>
<p>Thanks</p>
<p><tt>PDE1 := diff(f(x, t), t) = diff(f(x, t), x, x)+a*f(x, t); pdsolve([PDE1, f(x, 0) = 1])</tt></p>
<p>will give me</p>
<p><tt>f(x, t) = exp(t*a)</tt></p>
<p>which is indeed a solution of the PDE1</p>
<p><tt>PDE2 := diff(g(t, x), t) = diff(g(t, x), x, x)+a*g(t, x); pdsolve([PDE2, g(0, x) = 1])</tt></p>

<p>I'm trying project a plane onto a surface. Is there a direct command to do this?. There is a command to project a surface onto a plane but i need the oposite. Thanks!</p>
