Animate Numerical set of data
https://www.mapleprimes.com/questions/226887-Animate-Numerical-Set-Of-Data?ref=Feed:MaplePrimes:Version Maple 18
<p><br>
Hi, I am struggling a bit animating a result that I have.<br>
<br>
Let me explain.<br>
<br>
I solved numerically some equations for me movement of a rolling disc and a bar bolted to the center of the disc.<br>
<br>
So I have a long list of values for:<br>
<br>
x[h] for the horizontal position of the disc<br>
beta[h] for the rotation of the disc<br>
theta[h] for the rotation of the bar<br>
<br>
and so on...<br>
<br>
Then I created a procedure that, for a given instant "h", maple plots the disc and the bar correctly.<br>
<br>
Now I want to anumate this procedure that should depend only on the instant h and I cannot perform it.<br>
Maybe the error comes from the fact that there are not functions involved but numerical data, or maybe it is the fact that disc radius and bar lenght are assigned outside the procedure.<br>
<br>
Any help would be appreciated.<br>
<br>

226887Sat, 20 Apr 2019 19:35:56 ZDon_CaraotaDon_CaraotaHow do I plot each point of a parametrized curve with a different color in PlotPositionVector using curveoptions?
https://www.mapleprimes.com/questions/226879-How-Do-I-Plot-Each-Point-Of-A-Parametrized?ref=Feed:MaplePrimes:Version Maple 18
<p>I am using Maple 18 to plot iterates of a discrete map. A vector R1 is parametrized by the label b that runs from 0 - 2*Pi. The following initial iterate gives me a blue circle: </p>
<p>>a := 1.0<br>
>q := a*cos(b)<br>
>p := a*sin(b)<br>
>R1 := PositionVector([q, p], cartesian[x, y])<br>
>PlotPositionVector(R1, b = 0 .. 2*Pi);</p>
<p>Is there a way for me to assign a gradient colorscheme to each point of the circle, using b as parameter from 0 - 2*Pi? I have tried using the following, which does not give an error message, but it also just gives me a blue circle:</p>
<p>>PlotPositionVector(R1, b = 0 .. 2*Pi, curveoptions = [colorscheme = ["valuesplit"]]);</p>
<p>I am not sure how to use the vector and mapping options in the command >plotcommand(plotargs, colorscheme=["valuesplit", V, mapping]) to obtain the color gradient along the circle.</p>

<p>How can I draw together the function f(x,y)=(x.y^2)+1 and its tangent plane at the point (2,1,f(1,2)) in each of the following rectangles? </p>
<p>(Note that the equation of the tangent plane at the given point is z=x+4y-3)</p>
<p>a. 2<=x<=3 and 1<=y<=3</p>
<p>b. 2<=x<=2.1 and 1<=y<=1.2</p>
<p>c. 2<=x<=2.01 and 1<=y<=1.02</p>

<p>In the attached file, first, I use dsolve to analytically solve a system of equations. Maple solves it easily.</p>
<p>But, when I change the frequency (in the Sine function) of the second equation, Maple cannot solve it. Why?</p>
