I can not manage to figure out how to shade specfic regions under a normal curve. For example:

with(Statistics): X:=RandomVariable(Normal(0,1)): DensityPlot(X, range= -3..3)

I want to shade a region greater than or less than some X value.

Similarly, I would like to add a vertical line for some X value.

 

Thanks,

Hi there, I'm trying to plot a piecewise function. The problem is, the individual pieces are evaluated separately and maple seems to evaluate the numbers into square brackets.. As a result maple can't plot these, it can however plot it if I substitute the evaluated numbers and delete the brackets. Here's and example: > P := S[0]*(d+x)/(d-p); gives 10*([23/2]+x)/[8] and when I try either plot(p,x); or plot((10*([23/2]+x)/[8]),x) it fails however it can plot((10*(23/2+x)/8),x) any help would be awesome! thanks in advance

Hi I am trying to integrate the product of two matrices.  The independent variable is "x" and the constant is "L".  The two matrices are H and B.  I would like to integrate the two matrices on the x-domain from x= 0 to L.  Any help would be greatly appreciated.  Also I am new to Maple.  Is there a good beginner's book that would cover topics like matrix integration?  Thanks-Tom

H= [1, x, x^2, x^3]          (1x4 matrix)

Hi, would appreciate some help. Is there any command in Maple that would hep check general SARIMA equations? for instance, if we take the following model (0,1,0)*(1,1,1)_5, then the general SARIMA equation will be: (1 - K)*(1-K^5)*X_t = (1 + B*K)*(1+B*(K^5))*Z_t i.e. X_t - X_(t-1) - X_(t-5) + X_(t-6) = Z_t + B*Z_(t-1) + B*Z_(t-5)+ B*Z_(t-6) Is there any option in Maple that would allow me to check if this equation is correct? many thanx.

Hello,

I have 4 points in 2D and I want to plot them with different colors:

This works in Maple 12:

plots[pointplot]([1,2,3,4],[5,4,7,8],color=["Red","Blue","Magenta","Pink"]);
 

And I want to connect each other with line segments:

But this doesn't work:

plots[pointplot]([1,2,3,4],[5,4,7,8],color=["Red","Blue","Magenta","Pink"],connect=true);

Error, (in plots/pointplot) number of colors must match number of points
 

Hi

I am trying to use the following command

simplify(30/366)

The answer that I am getting is 5/61

how can I get the answer in numerical form.

For example 5/6 would be 0.082 if I round up the answer.

Using the calculator I get

0.081967213114754098360655737704918

After I round up, I get 0.082

Take care

Hi

How do I multiply Combitronics, using Maple

For example

with(combinat);
choose(7,6)

I want to multiply 7 Choose 6 with 5 Choose 3

If use I use the calculator I get

7C6 = 7

5C3 = 10

= 70


Take care
