Hello Everyone.
From :
To the question : Plotting the points of intersection on the graph ?
Thanks in advance for your time and help.
Solved! Go to Solution.
The points where the curve intersects with itself are plotted on the graph.... along with a lot of other points.
If you want the coordinates of the intersection points plotted in readable text next to them, you need to define a few more curves to get them in.
Refer to the great work "Creating amazing images with mathcad" by Byrge Birkeland for ideas on how to do that.
Success!

How many points of intersection on the graph ?
Sorry, I misunderstood your original question.
To solve the problem at hand, I would mathematically create the lissajous-shape in 3D, then make a projection of it on a (2D) surface and find the intersecting points of it.
Why the detour? because now you only have two expressions, and a single running variable. I see no path where that brings you to more than 2 solutions.
Success!

Emperically:
I greatly appreciate all of your time and help. Werner, Luc, and Fred. . I'm very, very happy. And I think I still need help with the two of question, the above, on cos( ) function :
Thanks in advance.
Best Regards.

So I have a query : How to rotate a graph (pi/2) clockwise and (pi/2) counter-clockwise ?

clockwise: replace the x(t) on the abscissa by y(t) and the y(t) on the ordinate by -x(t)
counter clockwise: replace the x(t) on the abscissa by -y(t) and the y(t) on the ordinate by x(t)
