I googled everywhere for this and most results just tell me what diff and D does...

Basically I have a function, let's say

f:= x -> x^2

How do I turn the derivative of f into a function?

I tried

fprime := x -> diff(x^2,x)

But tihs just shows me diff(x^2,x), instead of x -> 2x

Starting with Maple 18, the Print to PDF feature caused the document page to be hard-aligned at the left margin of the page. Maple 2015 still seems to have this problem / bug.

Does anyone else have the same problem? Has a work-around been posted? Is a fix in the works after nearly 9 months?

WHen I type:

I get nothing, a blank box. But if I change the code slightly, by squaring both sides, then it works.

What is the reason for this. I uploaded an image of the output:  http://prntscr.com/752mtd

Hi. I am having trouble with maples command "Cross product", i don't know why it doesn't work. Can anybody help me? This is a screenshot of the problem:

how to export a plot with its points  (x,y) from maple to excel

Hello Everyone

I am new to Maple and I have to find the determinant of the following matrix

Here k is a constant.

Can you please help me with it.

Thanks in advance.

Error, (in content/polynom) general case of floats not handled

How to solve this problem simply？

now the equation is

d2u/dt2-(2*d2u/x2)+d2u/dxdt=0    

initial condition: u(x,0)=1-(xsign(x)), abslute x<1,0 otherwise. Assume sign(x)=-1 for x<0, 1for x>0 

 Ut(x,0)=cos(pix), bslute x<1, 0 otherwise , he didnt give any B.Cs

so I would like to know the analytical and numerical sols, and plots for the wave at t=2,4

for Numerical:   delta x=0.1, delta t=0.025, range 0..4

Please how can Maple plot both analytic and numerical solutions on the same axes for this problem Ana_Nume.mw

U(x,t)= 2/3f(x+t)+1/3f(x-2t)+(1/3pi)(sin(pi(x+t))+(1/3pi)(sin(pi(x-2t)),

f(x)=1-x,abslutex<1, zero otherwise

Good day,

How can this be corrected ''Error, (in dsolve/numeric/bvp) initial Newton iteration is not converging'' see the worksheet here VT.mw

d2u/dt2-(2*d2u/x2)+d2u/dxdt=0    

initial condition: u(x,0)=1-x, abslute x<1   Ut(x,0)=cos(pix), bslute x<1 

B.C U(-4,t)=U(4,t)=0,   delta x=0.1, delta t=0.025, range 0..4                                      

Hi all,

I have been trying to figure out why when I run my 'code' maple keeps building up memory. I am currently writing X number of inequalities and plotting the results. I begin the script with the  'restart' command to clear the memory of any previous runs. But this does nothing to the memory allocated. I check with my 'task manager' window.

I've been scouring the internet for similar issues and basically is this a software problem? how can this be avoided?

'restart' does clear the variables but doesn't seem to make the freed up memory accessible.
