integrate ∫dx/√((x^2+1)(ln(x^2+√(x^2+1)))

In calculus of variations one may have the integrand of a functional F = sqrt(1+(y'(x))^2)

How do I get Maple to evaluate ∂F/∂y' ? (Maple doesn't recognise y' like Mathematica does)

( The answer is, of course, y'y''/sqrt(1+(y'(x))^2) )

hi,

i have an exercise ,i have to do for sunday:

a program on maple 13 of o numerical solution of heat equation for  semi-infinite rod where a finite quantity of heat is injected into the left end in the form of pulse instant

please i need your help.

I know

convert(sin(x),expln)

can convert sin(x) to expression which has "exp"

but how to produce the inverse operation?

Maple people:

I just installed Maple 16 on my home PC.  I prefer using Classic Worksheet Maple, so that I can actually tell what I have typed, and what I type appears in red typewriter font.  I also would like matching parentheses to blink when I enter stuff so I enter the right number of parentheses.  Maple works this way on my office PC, but I can't get it to work this way at home.  I could simply use regular Maple 16 (not Classic Worksheet...

Dear all,

need to take data(a,u) from eq1 and plug it in eq2

eq1 is:

eq2 is:

Then need to plot data (a,v)

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

I did that:

points:=seq([a,evalf(solve((alpha+(l+alpha)*u+alpha*k*u^2)*a=u*(alpha+(l+alpha)*u+alpha*k*u^2...

Hi,

I'm trying to write a function in an 'n' dimensional vector such that I can call upon this function in a loop to define hessian matrices, or simply evaluate the function value for a given input. Here's an example:

F(x,y,z)= 6*x^2 + 3x*y^2 - 1.5*z^3

which is a function in 3 dimensions with x,y,z representing the 3 components of a design vector.

I want to be able to call upon this function in a loop such as:

I was given the following MGF and need some help determining the E(X), Var(X) and P(4.1<X<4.7) using Maple

MGF of X is M(t) = 1/(1-3t) , t<1/3

How can I get Maple to do this for me?

Thanks again :)

Is there a possibility translate Maple code to Reduce code ?

Hello,

do 3D-OpenGL-Graphics in Maple 16/17 on Linux-x86_64 (openSUSE 12.2/12.3)  work with Intel HD 3000/4000 Graphics?

Thank you very much.

Maple 16 is crashing when saving. I have this problem in both

my desktop and laptop (PC, Win7), classic and standard worksheets.

I noticed that short files present no problem, but whenever the

worsheets are, say, more than 5 screens length, Maple 16

crashes when saving.

Anyone with the same problem? Any solutions? Thanks

Hi!

I need to assign a name to a result calculated from a system of equations. In this case, i've got 2 equations and 2 solutions. I want to assign a name to the each of the solutions.

solve({-a+4*b = 0, 2*a+7*b = 2}, {a, b})

{a = 8/15, b = 2/15}

How do i assign a name for a and another for b?

I mean not open these files, and ctrl+A select whole file and copy to one file.

THis is what I have so far.. is there anyone who can help me with this?

Let f(x) = 1/9*x^2, o<x<c

Find c so that f(x) is the pdf of a random variable X.

I have come up with this and was wondering if I could get some help. I cant get it to paste in, but I have

uploaded the file.. Please assist if you can.
