Computing a limit by maple.
https://www.mapleprimes.com/questions/226481-Computing-A-Limit-By-Maple?ref=Feed:MaplePrimes:Version Maple 2018
<p>I want to compute a limit via maple and that it will show me the way how to compute the limit.</p>
<p> </p>
<p>The limit is:</p>
<p>\lim_{epsilon ->0, t\in [0,1]} 1/(exp((-1+(1-4*epsilon)^(0.5))/(2*epsilon))-exp((-1-(1-4*epsilon)^(0.5))/(2*epsilon)))*[exp((-1+(1-4*epsilon)^(0.5))/(2*epsilon)*t)-exp((-1-(1-4*epsilon)^(0.5))/(2*epsilon)*t)]/(exp(1-t)-exp(1-t/(epsilon)))</p>
<p> </p>
<p>According to my book it should converge to 1.</p>
<p>I tried manually but got stuck.</p>

https://www.mapleprimes.com/questions/226466-Map-A-List-Of-Functions-Expecting-Two?ref=Feed:MaplePrimes:Version Maple 2018
<p>Hi there. Thank you all in advanced.</p>
<p>The general question is how to pass a pair of values to a list of functions that expect that pair of values as input.<br>
I already know this solution for passing a list of values to a list of functions that expect one value as input.</p>
<p style="margin-left: 40px;">map(eval~,[f(x),g(x)],x=~[p,q,t])</p>
<p>Well f(x) and g(x) take every element of the list, but what if f(x) and g(x) expect two values. The concrete case is to pass p and q to iquo and irem. The following were my tries:</p>
<ul>
<li>map(eval~,[iquo(x),irem(x)],x=[p,q])</li>
<li>map(eval~,[iquo(x),irem(x)],x=(p,q))</li>
<li>map(eval~,[iquo(op(x)),irem(op(x))],x=[p,q])</li>
</ul>
<p>I searched and found some partial related topics in the site but not quite with this approach.</p>

<p>Dear Experts,</p>
<p>I am new user. I need your help!</p>
<p>I have numerical values of omega (w) and a2F(w) (500 rows). I need to do cumulative summation to get lambda(w) using lambd=2 int (a2F(w)/w dw). Please help me how can I do it?</p>
<p>Best Wishes,</p>
