hey primes please i need help. i´m trying to create a procedure capable to find an arbitrary distance. at some point in loop clause, is important to 'unassigned'  the variables solved and here where i have problem. it work fine in...

So far, my math group has the entire roller coaster plotted using spacecurves on a 3D plot on Maple. The only issues is now we need to take the derivative between the different sections we created in order for there to be no corners or spaces; basically to make sure the "coaster" runs smoothly.

We get how to do it on paper but we're running into some difficulty doing it on Maple. My question is, how the heck do we do what I just said we wanted to do.

Hello,

I am trying to plot the solution for eq1 and eq2 for different values of mu.  When I plot  this:

 f := proc (x) options operator, arrow; mu*abs(F[N]-g)*signum(x(t)) end proc;

it works.

When I do the same for the solution it won’t work.

Please any help or advise.

This is the code:

> restart;

> with(plots);

> with(DEtools);

> k := 100; L := .25; M := .5; g := 4; mu := 0.2e-1;

Q3) Write a procedure, isTriangle, to determine if any three given

 numbers represent the lengths of the sides of a triangle.
       The procedure should be able to deal with any input.

I have done the following and get an error

isTriangle:=proc(a,b,c::nonnegative and numeric)
if (a^2+b^2)=c^2 then print (a,b,c "represent the sides of a triangle")
end if;
end proc;
Error, unexpected string

Thanks very much for your help!

So I've done this so far:

Marks:=proc(m::nonnegative, numeric)
if m < 40 then print (m, Fail)
elif m < 50 then print (m, `Third Class`)
elif m < 60 then print (m, `Lower Second Class`)
elif m < 70 then print (m, `Upper Second Class`)
elif m < 100 then print (m, `First Class`)
elif m > 100 then print (`error`)
end if;
end proc;
proc(m::nonnegative, numeric)  ...  end;

Hi,

Suppose you have an unknown function y(x)  that is 2*Pi periodic, i.e. (y(0) = y(2*Pi)). Is there a way to declare this in Maple? The reason I want to do this, is that if I integrate the derivative y'(x) of  this unknown function on [0,2*Pi]I would like Maple maple to be able to recognize that:

int(y'(x),x=0..2*Pi) =0

Thanks

How can I precisely control the camera position using veiwpoint in an animated  multibody display.

My question arises from an post by John May, http://www.mapleprimes.com/maplesoftblog/95570-Klein-Bottle-Plot

I have attempted to use the excellent articles with multi-body displays and was forced to use plots[display] rather than the plot3d function as described. It went well but...

In a plot of y=x^2 how can one choose to have no tickmarks except for at given points say x=2 and x =8 and of course on the corresponding y values?

I created a quick procedure to produce a violin plot and I would like some help to make it better. 

I would like it to show a more accurate distribution of the data, I interpert the graph as the data having negative values which of course there is none.  How can we fix that? I realize we can just set the range=min(data)..max(data) but then I loose the violin tips and I would need to place a line to cap the top and bottom.

So how can we create a violin...

Hello. I am trying to do a project. Howerver the following code is causing Windows 7(x64) to error.

Hi, 

When I try the example of a histogram plot from the help system (under Statistics, Histogram), I get an error.

The example (entered in document mode) and error follow below.  Can someone please shed light on this?

with Statistics; with(plots):
N := RandomVariable(Normal(0, 1)):
A := Sample(N, 1000):
P := DensityPlot(Normal(0, 1), color = "Niagara Red"):
Q := Histogram(A, averageshifted = 4, style = polygon, color = "LightSlateGrey"):

Maple plots pareto charts slightly different than what I usually see.  It might be nice to include an option in the pareto to flip the axis.  But I think maybe the reason maple has pareto plotted this way (having the x and y axes flipped), is because the x-axis is unable to angle descriptors (an option I have asked to be added in the past)

Using the pareto example from maple help, when I rotate and flip the chart from plottools where did the y axes labels go?
