Hi maplers!

Me and some friends have been wondering for quite some time now, about the possibilities based on the folowing calclation:

b,c:=1,2

equ:=a^2=b^2+c^2 (just a commun equation)

Now comes the problem, since i need maple as a tool for making reports and whatever comes in handy, i need to think at the visual stuff too(since my teachers want it, *SIGH*). Then is there a function that just inserts the varriables into the equation, so thre resualt would be something like this:

Calc( equ,'input')

 

ok, let me see if I can explain. If we run the below code we will get a matrix with nstock stock price, a matrix with returns, a

correlation matrix of returns and a plot of the nstock stock prices. (the code work I hace checked it by copy past)
 

Hi, I'm traying to maje a double integrate of P(A(t+Deltat),A(t)) , the first one in in untion of dA(t) and the second one is in fuction of dA(t+ DeltaT). How can I indicate in Maple Deltat?  Is it possible to integrate in function of A(t)?

All variables are constant, except A(t) and A(t + Deltat),

> F:=proc()

How do I do this?  I want it to go from say real to natural and specify the function after.  I would like to be able to do this so I can graph and find specific outputs.

 

Thanks,

All:

Sometimes when I integrate through an infinite discontinuity Maple outputs "undefined" as in the simple case: int(1/x,x=-1..1);

and with some I get "Infinity", as in the case: int(sec(x)^2,x=0..Pi);

What is the nuance in play here?  Is it with the math or with Maple?

I was hoping to give my calculus III students a short introduction to using vectors in Maple.  I wanted a few simple things like plotting vectors in three space.  I loaded VectorCalculus.  Got the dot product and cross product to work, and I can plot one vector -- although it looks more like a telephone pole with a cap than a simple arrow.  But despite all my attempts to give plotvector a list of vectors, I am completely unsuccessful.  There has got to be a better way.  I'm quite frustrated after searching through documentation for several hours.  I'm cert

hi,

how do I write a procedure to update a correlation matrix when I move the slider?

hey guys i need help answering the following questions using maple for my calc II class... any help at all would be great... thanks 1.) Find the area of the region that is bounded above by the curves f(x)=10ln(x) and g(x)=4-(x^4)-x and below by the x-axis. Then for the next two questions use the region that is obtained in question 1. 2.) Find the volume of the solid obtained by revolving this region about the x-axis. 3.) Find the volume of the solid obtained by revolving this region around the line x=4. Thanks guys

My problem statement is here - mathbin.net/5767

Now,  I want to know if this would be relatively simple to plot?  I hope to find a table of the non-trivial zeroes somewhere to save maple computing them.  If I did that, does anyone know how I would plot this?

For anyone interested, this is supposed to simulate the prime counting function.

Thanks,

Hey there everybody. I've been working on the Project Euler (projecteuler.net) problems for a while now, using Maple or J to solve the problems. Some of the problems involve using palindromes or testing for palindromes. I know I can convert the number into a string, reverse it with StringTools, and then parse it back into a number, but that requires a lot of time and resources (the PE problems should be solved in under 1 minute).

I'm trying to add a path for the Syrup library to a Maple.ini file in a Windows XP system. The existing library path that shows when I execute libname is "F:\\Program Files\\Maple 10/lib" The Syrup library that I want to add is at F:/Program Files/Maple 10/Syrup/maple.lib What is the correct syntax for getting this path into a maple.ini file? phil kenny

I have the following equations currently in a maple program. I would like to solve for POc in terms of miu, uA1 (or uA2 it doesn't matter since they are equal), L, LTJ, h, b, and PT. I tried the solver, which does not work. I also consider the eliminate function, but I played with it too long and have now given up. Any ideas?

uT1:=uB1*h/H;

uB1:=uTJ1*b/h;

uTJ1:=uA1*h/b;

uA1:=uF1*h/h;

uTJ2:=(PTJ1-PTJ2)*b^2/(3*miu*LTJ);

uA2:=(POc-PTJ1)*h^2/(3*miu*L1);

uB2:=(PTJ2-PT)*h^2/(3*miu*(L-L1-LTJ);

eq1:=uTJ1=uTJ2;

eq2:=uA1=uA2;

Can anyone please tell me how to remove the box outside of legends? I cannot find where this is documented.

I have newbie problem with these two equations:

f(x) = 0.5x-3x-x+x+10
g(x) = xe

I am supposed to draw them in Maple and solve f(x) = g(x), this is what I've got:

f:=x->0.5*x^4-3*x^3-x^2+x+10;

g:=x->x*exp(1)^(0.5*x-1);

plot([f,g],-4..8);

Now I get the drawing and it seems okay, but then I try using solve to do f(x)=g(x)

solve(f(x)=g(x));
