Hi, I have a function y[x which behaves as an inverted parabola. By using the command max(y) I can find the maximum y value, but I would also like to find the associated x value. What command can I use to find the x value? Thanks!

How to extract a symbolic only function to the numeric processor
Some functions are only recognized by the symbolic processor. I am looking for a way to encapsulate some of these functions so they are available to the numeric processor via a normal function call. An example with one such function - Si(x) - is shown in the attachments, with various schemes I have tried. The element-by-element approach in item 2 works for assigning values to an array of arguments, but is a bit more awkward than I prefer. My attempts at defining a function in items 4-6 haven't worked.
Is there a way to define a function that is recognized by the numeric processor that does effectively what is in item 4, but works? If it can be done for a scalar, then I would assume that vectorizing this function would allow evaluation with array arguments, since the symbolic encapsulation is isolated in the scalar function definition.
If responding with a file, please save in mcd11 format.
Thanks,
Lou

How do you solve for a variable?
I was just wondering how do you solve for a variable in MATHCAD. I have a function defined as
h(v,k,c):=(k/c)(v/c)^(k−1)exp(−(v/c)^(k))
This is a weibull distribution fucntion. k and c are already defined constants k = 1.5 and c = 15. I take the derivative
dh(v,k,c):=(d/dv)h(v,k,c)
I want to set it to zero and solve for v but when I set dh(v,k,c)=0 I get a 'variable is undefined error'. Anyone know how to set the equation equal to zero and solve for v?

License borrowing in Prime2
Using a floating license, does anyone know if it is possible (and how) to borrow a license with Mathcad Prime 2 for longer than a week.
There seems to be no way to set the time in Prime2.

PTC Mathcad: How to print an e-book in its entirety
I'm attempting to create an internal e-book for our company which can be used to perform a complex computation we are working on. However, after creating separate xmcd files such as: splash screen, TOC, and some content pages, I cannot figure out how to print the entire book. I would like to be able to have the user print the book as a reference, but still be able to create their own version usign the e-book copy and paste function to their own document.
Does anyone have any idea how this can be done?

Dear Folks!
I found the solution to the problem mentioned:
The problem is that MathCad 14 does not work correctly under windows 7 (32 and 64).
The solution:
Install MS Visualstudio 2005 prof edition before installation of MathCad. (I do not know wich components of it helps, but it solved the problem)
I hope it helps for someones!

AUTOMATED (PROGRAMMED) CALCULATIONS
Hello everybody,
I have attached a MathCad 15 worksheet. I would like to make tables of the following parameters for 3 values of alpha and for different rhos.
rho values: 2, 5, 10, 20, 30, 50 and 60
x1c, x2c and x3c corresponding to alpha=0.50, 0.45 and 0.40 respectively.
Q1c, Q2c and Q3c - same thing.
y1c, y2c and y3c - same thing.
Please go to the "Xc, Qc and Yc Section" on the worksheet.
Also, I would like to make some graphs of these parameters.
Thank you so much for the time and help.

PS final results as an array would be OK. I guess, it can then be exported to excel. OR, can MactCad produce tables?

xmcd-Files in browsers
Does anyone know how to avoid that a xmcd-file is displayed by the browser (as XML) rather than opened with Mathcad when clicked on in a browser window.
Its especially annyoing when I use the webinterface of a mailer instead of a dedicated program like Thunderbird or Outlook.
The effect is there in any browser but it seems not to be a Windows installation issue as the extension is correct registered in Windows with Mathcad and double clicking a xmcd-file works as expected in opening the file with Mathcad.
This behaviour is rather annoying as I am forced to save that file to disk and open it from there. Asking people to send files in xmcdz or even mcd format has proven not to work really good ;-)
In FF under extra/options/applications I can see the entry "Mathcad-document (application/x-mathcad-xmcd)" but whatever I set the desired action to (ask, open with Mathcad,..) the reaction is the same - Firefox displays the file as XML as do Chrome, IE and Opera.

functions within functions
I am wondering how one uses a function within a function. For exampe:
t=0,1..10
f(t):=2*t
then t and f(t) are vectors of length 10. t contains the 11 numbers 0-10 and f(t) contains the 11 numbers 0 through 20
Now, I need to use the values of f(t) in another equation, like:
g(f(t)):=10*f(t)
I should be able to get a vector of 11 numbers ranging from 0 to 200, but I can not make this work.
In my actual problem I am using an ODE solver to get the values f(t) and so I can't just change the algebra. I need to use the values of f(t) in another equation? HOW DO I DO THIS
