How to extract from the implicit plot when
https://www.mapleprimes.com/questions/229156-How-To-Extract-From-The-Implicit-Plot-When-?ref=Feed:MaplePrimes:New%20Questions
<p>Hello.</p>
<p>I'd like to extract numerical data from the plot of a implicit function and write it to the txt file. But, unfortunately due to a strong oscillating function and as a consequence extremely dense meshgrid I got a message that [Length of output exceeds limit of 1000000]. How to resolve this problem? Below is my code</p>
<pre class="prettyprint">
restart;
R0 := 1+w_c*(sum((2*(-1)^(n+1)*Pi^2/n*n)*t*sin(2*Pi*n*mu/w_c)*cos(Pi*n)*exp(-2*Pi*n*G/w_c)/(w_c*sinh(2*Pi^2*n*t/w_c)), n = 1 .. 3000))/Pi-mu;
with(plots, implicitplot);
G := 0.; t := 0.1e-2;
R1 := implicitplot(R0, w_c = 0 .. 5, mu = 0 .. 3, gridrefine = 10):
data := getdata(R1);
</pre>
<p>Thank you in advance.</p>

<p>Knowing X's PDF is a piecewise function,=cx^2 for 0<=x<3, 0,otherwise</p>
<p>Q1 solve P{-1<=X<=1}</p>
<p>Is it possble to use CDF solve?or I must use calculus?</p>

https://www.mapleprimes.com/questions/229154-Showing-An-Arrow-On-A-Curve?ref=Feed:MaplePrimes:New%20Questions
<p>Dear Friends</p>
<p>I would like to know how I can show a simple arrow on a curve in a plot. For example for the simple sample y=x^2, for x>0, I want to show with an arrow in the figure that the trajectory begins from the point (0,0) and tends to come to the point (3,9). Or any other examples you want.</p>
<p>Thanks a lot</p>
