Old problem with an ellipse
https://www.mapleprimes.com/questions/230535-Old-Problem-With-An-Ellipse?ref=Feed:MaplePrimes:Version Maple 2018
<p>A triangle ABC with fixed B and C vertex is considered in the plane, A being variable so that b+c remains constant and equal to a given length L.<br>
We call P, T, T' the points of contact of the exinscrit circle in the angle B with the sides BC, AB and AC respectively.<br>
Show that P is fixed and is one of the vertex of the ellipse described by point A. What are the locus of T and T'? How to animate the drawing when A move ? Thank you.</p>

<p>In the plane, an ABC triangle is considered for the vertices B and C are fixed, A being variable so that b +c remains constant and equal to a given length l. (b=distance(A,C), (c=distance(A,B)<br>
How to show that the product tan(B/2=*tan(C/2) remains constant ?</p>

https://www.mapleprimes.com/questions/230399-How-Can-I-Extract-A-Bestfit-Function?ref=Feed:MaplePrimes:Version Maple 2018
<p>Good day to all.</p>
<p>I have a data set consisting of 12 points in the x-y plane. These points form a periodic pattern and I was wondering if it is possible to obtain a curve that is a best-fit for these points. I have reason to expect that this pattern will repeat for successive points (i.e. points 13, 14, ..., 30).</p>
<p>Does anyone know of a way to obtain a function that can represent this behavior?</p>
<p>Thanks for reading!</p>

<p>Whoever designed Maple's user-interface thinks very differently from me. How can I insert a 2nd section into Chapter 1? There's no space between the end of Section 1 and the end of Chapter 1 for me to put the cursor, so where should I put the cursor, and what should I do?</p>

<p>What do I need to do to the "2 + 3" in the attached Document in order to make it evaluate? I know about F5 to switch between Text and Math modes, but that's not enough to get me where I want to be. The "2 + 3" is already in Math mode, but that's not enough to get it to evaluate.</p>
