Hi, My name is Remon. I am first year student in calculus 1, I want to be a financial engineer, I will study finance and I will do my best to study mathematics as well. I need to learn Calculus with Maple. but I do not really from where should I start? Is there any video training for Calc 1,2, 3 that I can buy to learn ?? If there is any advice to help me out to reach my goals I will be very thanksfull.

In trying to solve for a difference quotient, I've entered the following:

Why does the second solution appear in the way I want, but not the first? Is there any way to get the first to display in the same way as the second?

Thanks in advance.

I have 2 worksheets open, in my maple16 screen

In one of them I do

save rrK,"ttKazem.m"

and can easily restart and after that read "ttKazem.m" in that worksheet

but in the other worksheet, unfortunately read "ttKazem.m" yields:

Error, Could not open 'ttKazem.m' for reading

That's really wonderfull. Any idea?

Hello all

I have a set of differential equations and its numerical solution, for two functions. Here's the worksheet (just a part of it, I don't need the rest)

##########################################

eq1 := diff(W(r), r) = -(1-beta*(W(r)-W0))*(M(r)+4*Pi*r^3*p(r))/(beta*r*(r-2*M(r)));

eq2 := diff(M(r), r) = 4*Pi*r^2*rho(r);

W0 := solve(thetaR = theta0-W0, W0);

r0:=10^(-5);

rf:=10^20;

# ini := evalf({M(r0) = 0, W(r0) = W0});

Hi everybody

my eq is,

eq:=diff(u(x,t),t)+diff(u(x,t),t$3)+diff(u(x,t),x$2)=0

my question is how to calculate  diff(eq,diff(u(x,t),t)) 

maple fsolve function fails to give correct result for the following problem

aa:=evalf(fsolve(sin(xx*a)=0,xx,0..pi));

if i ignore a coefficient, the results will be correct.

Does someone know why?

Does maple have any function without such limitation?

How to include/code/type such type of boundary conditions in maple?

Thanks

Hello. I am creating a custom component similar to the one that maplesoft has as an example (the discretized counterflow heat exchanger), but with some diff. The problem is that when i execute dyamic systems i get an error saying:

Error, (in DynamicSystems:-ParseSystemInputs) cannot match the arguments to an appropriate system

Is this a problem on my equation (something that i may have forget) or is another thing? Are the arguments type of dynamic system in the right "type"?

Hello,

1. Is it possible to create a function file in Maple and call the function(file) from the main program(like Matlab?). If yes, please give me an example case.

I want to create a function file which has the general input terms and call the function from another script file without copying/running all the code.

2. Is it possible to run 'recursive function' in maple?

3. How can I create library of my function files?(like in Matlab I can create...

I have a vector containing data which is m*n long (ie from 1...(m*n)) and I want to convert it to a matrix of m columns and n rows.

What's the quickest and most efficient way in Maple to do this?

Dear All,

I am trying to solve the following equation but I don't know what I am missing:

A:=0.0032*cos(19*theta+18*w*t);

B:=0.0014*cos(19*theta+18*w*t+phi);

T:=A+B;

theta = theta,  w=w and t=t  phi =Pi/6

when I try to add them it gives very long answer.    

Your help in this regard will be highly appreciated.

Best Regards

Dear everyone,

I'm trying to create a list, L, of all vectors of length l with values in a small discrete set S (eg S:={1,2,3}). I can do this for any particular l by the following code:
(Assume l:=5)

L:=[]:
for i_1 in S do
for i_2 in S do
for i_3 in S do
for i_4 in S do
for i_5 in S do

Hello all

I have a worksheet where I use a .txt file as input (link in the end). Then, if I try the following command

bettermcproc(10,2*10^5,10^(-6),-60);

it fails, saying it cannot calculate. If, however, instead of using the input file I put it all in the worksheet it works perfectly. I know I could just put it all in the worksheet, but I want to save some space and time, since I use the same input file to do lots of different things.

Thank you all for the help

Find $M=sin(54°)+cot(7.50°)$

Greetings,

Is it possible to change the font size used for existing Maplet applications? If it is possible to do so how can I make it? I want to increase the font size because the natural resolution of my screen is pretty high and the numbers are barely legible in any Maplet application. 

Thanks in advance.
