hi, i have an equation and i cant simplify it. i claculate with hand and i know the answer but with maple i cant give answer.

       aa:= sin(theta + tao s) cos(d s) + p d cos(theta + tao s) sin(d s)

        bb:=  sin(theta + tao s) sin(ds) - p d cos(theta + tao s) cos(d s)
                 cc:=         ...

Hi,

I am not very familiar with maple but have a problem that is probably very easy for an expert. I have the coordinates of three variables, but no specific function of it. I want to create a 3d graph with these coordinates but do not know how. I have done it before with a specific function, but do not know how to do it with solely the coordinates, I work with Maple 12. Could somebody please help me, it is very important for me! thanks in advance,

Hi! I am trying to solve this system:

 but I have a problem.

Y was trying to plot this fuction f(x)=3x^2-2x when x= 0.1,.09,...,-.1 but i can't i'm a new user.

Augh, this is hurting my brain.  This homework assignment (still the same one as before) is my first experience with Maple.  I'm trying to learn the semantics of the language as I go, and that's been going well for the most part, but there's this one thing that has been bugging me to absolutely NO END:  Logical operators.

Here's what I understand after a lot of internet searching and Help browsing:
-There's two sets of very similar operators. ...

I was trying to solve 3 equation with 3 unknown. After solving the problem by Maple, I put the answers in the primary equations and I expected  the result for each equation be zero. I did it just for testing the correctness of answers.  But unfortunatly one of the answer is not zero. What is the problem? I attached my worksheet to this post. Improved_GU.mw

Got the script below, was trying to plot data from excel in maple and get a curve fitting. i was trying to get the residual meansquare for the curve fitted (last line script), but the script did not return anything. see attached. please let me know what was wrong.

hello

This is what I have written out in Maple, and I have been trying to plot into a graph, but am having no luck at all.  Do you have any advice for what my next step should be. I'm using a simplified version of Brain and Cousens model.

y := (x) -> (d+fx)/(1+h*x^b) , x > 0

b := 2; d := 1; h := 1;

This is the question: Let b = 2, d = 1 and h = 1 

Hi

The attached document is my Mat assignment. When I open the file, it says that "There were problems during the loading process. Your worksheet may be incomplete." And it only shows a blank worksheet. The worksheet has been created in Maple 13 and modified in Maple 14. The problem occurred then I made the last part of the assignment! Is there any way to retrieve the file?

I hope you can help me...

Regards

that was my ouput. I'm just trying to take the limit as x goes to -inf, as you can see.

Does it just mean that my graph is diverging as x goes to negative inf?

thanks!

How would I plot the following complex function?

f(z) = z² , Domain = {z = x + iy | x < 0 and y > 0}

Hi,

Im trying to plot the piecewise function that looks like this:

(1-x^2)/((x-1)(x-3)) for x<1 and x>3

x for x=1..3

I have entered the function like this:

f:=x-> piecewise(x < 1, ((1-x^2)/(x-1)(x-3)), x = 1 .. 3, x, 3 < x, (1-x^2)/(x-1)(x-3));plot(f);

And plotting it with:

plot(f);

And then i get this result:

Hello, I'm new to Maple and I'm having some difficulty using the program.

So I'm asked to "Find the numerical (decimal) value of the function h'(x) for x = square root of 2."

I tried typing in: D(h)(sqrt(2.0)); however it returns: D(h)(√2)

I think I may have typed in my prior coding incorrectly.

> h := G(f(x));

> h := unapply(h(x), x);
 
> dh := D(h);
     ...

I tried to run a fairly simple list of commands:

weight := k -> if(k = 2, 1/2, 1)

sum(weight(m+2), m = 0 .. 0)

the expected result should be 1/2 - which is weight(2). But Maple returns 1 for some reason.

Is this a bug in Maple or did a make a mistake in my expressions?

Many thanks in advance

 I was told to "Make a plot of the function h(t) which shows all the intercepts, vertical asymptotes, and extrema that you have determined above." And how might I go about doing this?
