Good morning sir,

Please help me out to fit the Gompertz growth model using Maple.

with thanks & regards

Can someone tell me how to solve the copy&paste problem? Every time i want to copy&paste an integral i get this error "Parts of the expression are ambiguous please select one of the suggested meanings".

Its really frustrating! 

Good afternoon sir,

Some of the Problems related to Numerical Analysis consuming much of time when solved using Maple.

I noticed at the bottom of Maple worksheet Evaluationg in animated form for a very long time.

How to overcome this type of problem in Maple. Please kindly suggest the best method.

with regards

Good afternoon sir,

I am getting frequently error message while finding the approximate value using False Position method

for the function f=1+x-2sin(pix) 0<=x<=0.5

If I replace pi by 3.14 it is giving the result. Please solve this problem for me.

with regards

I have to calculate inverse laplace transform of a function that contains branch point at zero and infinity. Is there any procedure in Maple to calculate ILT with branch point Analytically.

In the application example SignalGeneration, I click on the button "Play Waveform" and get the message "This option is only available on the Windows platform. Your platform is X86 64 WINDOWS". Does it really mean that I won't be able to play audio file in windows 7 64? If not, how can I solve this problem ?

Thank you!

Doing a pointplot([x1,...,xn],[y1,...yn]) is no problem but I have lists [y11,...y1n] [y21,...,y2n] ... [ym1,...ymn] each be plottet at [x1,...,xm] in 1 plot.

That means:

plotting 

[y11,...y1n] at x1

[y21,...,y2n] at x2

.

.

.

[ym1,...ymn] at xm

What is the easiest way to implement this?

I am trying to illustrate the effects of using finite-precision arithmetic on solving certain linear systems using elementary row operations. I am able to set Digits to the desired level and use the RowOperation command for each individual row operation. I would like to be use say, ReducedRowEchelonForm or LinearSolve with the desired level of precision. Is there anyway to force Maple to use whatever number of digits when using commands like ReducedRowEchelonForm or LinearSolve?...

Now I have written this for loop just intuitively but unfortunately it doesnt work:

x(0):=0.5

for N from 1 to 100 do

x:=proc(n) option remember; eval(r*x(n-1)*(1-x(n-1)),r=4/(100)*N) end proc;

l(N):=[seq(x(n),n=20..100)]

end:

What's the specific problem maple has?

Edit: problem solved: 

for N from 1 to 100 do

x:=proc(n) option remember; eval(r*x(n-1)*(1-x(n-1)),r=4/(100)*N) end proc;

On the test I had today I was asked to find the derivative of x^3+3*cos(x) using the definition of a derivative. The (f(x+h)-f(x))/h type.

So i set my function and then used the definition and then tried to simplify. Unfortunately the bottom h is still there so when I try to evaluate the function when h=0 it returns an obvious problem. It can't divide by zero. Usually when I do this the h on the bottom will be canceled out, but it wouldn't do it for this one. Does...

following expression doesn't simplify to 1

conjugate(1/sqrt(I*t*lambda+m))*sqrt(lambda^2*(t^2)+m^2)*(1/sqrt(I*t*lambda+m))

Now I did use assumptions on any variable

specifically: assume(lambda>0,t>0,m>0)

Then I tried radnormal, simplify, evalc, combine(expr,radical)

But none of these work.

Can maple use a Differential Operator somehow in the following sense?

Instead of expanding (D-p)^n where p is a constant and D the differential operator and n an integer and then in each term writing D^n(f) for some function can I just leave the expression as it is like

(D-p)^n and acting on everything on the right?

While expanding a lengthy expression I get these in mein series expansion

ln(e)^4*cos(argument(e)/z)^2

I guess e is just exp(1) so why does maple not simplify it to 1 ?

and what shall arg(e) mean?

is it zero?

I'm supposed to do the following. I tried to ask my teacher how I could go about doing it and she told me to just figure it out. I am supposed to find the linear and quadratic approximations to the function f at x=a. Then, I'm supposed to sketch the graph of the function and its lienar and quadratic approximations.

The linear approximation is:

P₁(x)= f(a) + fprime(a)*(x-a)

The quadratic approximation is:

P₂(x)= f(a) + fprime(a...
