Hello

I am trying to plot a harmonic oscillation, but maple keeps rewriting my defintion so when I plot, it gives me a wrong graph...

How do I stop it from doing this, I am assuming it is this that causes the problem, and not the plot command?

Here is what I get:

And here is what I want - made with geogebra.

If it isn't the definition that is the problem, what plot command should I be using then?

Hello again,

I had to download an add-on package to make this graph in the first place, so it might not be possible to help me.
Additionally, I have no idea how to translate "sumkurve" from my native language (danish) to English, which is also why I had to download the add-on package in the first place....

As you can see in the picture below, I have a table at the top, with a matrix underneath, then with the "plotSumkurve(A)" I got this beautiful graph that also shows the quartiles (kvartiler).

But what if I wanted to find the Y value that corresponds to X=12, any idea on how to do this would be great appreciated.

With gratitude,
Toby

Hello,

I am not sure how exactly to word my question, so forgive the mess ahead.

Say I have two points, A and B, and I want to make them variables in Maple so whener I refer to A, it refers to the point A.

Currenty what I do, is I write the line "A:=(x,y,z)" enter and then the same for B, but what I would like to do, is maybe write both the variables in one statement - something like "A,B:=(x,y,z),(x,y,z)", so when I am solving problems with 5-10 different points, I won't be filling up 1-2 pages with statements on variables and their values.

I am assuming this is a possiblity, but I haven't been able to find anything on-the-line that could show me how to...

Example picture - where A and B should have had been in the same statement, so when I find the vector between them it'll still give the correct answer.

Any help is appreciated here :)

With gratitude:
Toby

Greetings Sirs,

I have recently aquired Maple for some mathematics, and being a new user, I basically google for everything at the moment.

While it has gone well so far, I seem to have hit a bump that I cannot figure out.

I have a function: f(x)=3.2+0.4sin(1.25x), 0<x<5

Trying to find the places where "f(x)=3.5" would normally be done with the equation "3.5=3.2+0.4sin(1.25x)", and when I solve for the equation in Maple I get a solution too.

Problem is though, I know there is supposed to be multiple solutions. Having used wolframalpha, and being capable of seeing the plot in Maple, I know there is two points within the period "x=0..5" that is the solution.

But when I try to solve the equation, I get only one solution per solve, and the second solve doesn't make much sense for me. These are what I use:

As you can see, in the first solve the entire function is being taking into consideration, yet I only get one solution... In the second solve I have tried specifying a period, but I still only get one solution.

Basically any help here is appreciated, because from what I understand, having read google, the solve command or fsolve command is supposed to give multiple results if they are there.

With appreciation,
Ciesi
