Find y(1) and y′ (1), and then plot y(x) and y′ (x) on the same graph over
the range 0
≤ x ≤ 1, if y(x) is the solution of the initial-value problem corresponding
13
to the differential equation y′′ + sin(xy) = 0 and the initial conditions y(0) = 1 and
y′ (0) = 2.

 

That's my question, here's my input so far.

who know how can i solve or plot a two unknowns equation in MATLAB like implicitplot in maple?

Hi

I've got some problems with the upper limit of an integral, which is a (known) function of a parameter.

When I try to evaluate it for a particular value of the parameter (M), Maple does nothing:

 

Hi I'am using a simple method to simulate solutions of ODE's with a precision that requires to do 80 million evaluations of my functions. Since this does thake a while, I was wondering if it would be possible to display some type op progress bar or to show on the screen how many steps have already been done. Is it possible to do this inside a proc environnement? Thanks in advance Pieter

I cannot find the Statistics Phi. For example when z is 0 Phi(z)=0.5 When z=0.50 Phi(z)=0.6915 I cannot find this anywhere in Maple. It's the Cumulative distribution function of the standard normal distribution Φ(z)

I am just curious as to how much money my fellow mathematicians would consider to sufficient to pursue a Martingale betting strategy? I would suspect that 20 000 ( assuming an initial betsize of 1) would be sufficient. Then you can handle 13 sequential losses.  However, it is a bit risky because let say you get 14 sequential losses then you will lose all 20 000 , he he

 

 

I copy the "lim" command in the Help,it seems doesn't work easily,what should I do make it work,

Hello,

I'm simply trying to define a piecewise function but maple inserts some command I can't even find in the help.

f:-x->piecewise(x<-1,3x^2-5,x=-1,5,x>-1 and x<=4,3x+1,x>4);

and I get in blue

hi

im a complete newbie, i'd like to write some MapleTA questions which involve the inverse of the Gaussian cumulative distribution function, N(x).  [N(0)=.5, N(-x)=1-N(x)].  I know maple has this function in its statistical package, but i can't figure out how to access it, apply it, or assign its output to a variable in MapleTA.  What I need, basically, is the ability to compute something like $a=N($d1) and $b=N($d2) and use these to find a numerical answer to a problem. 

Hi

I'd want to labels the two axes of my desityplot with a greek letter (eta) and the calligraphy form of M (I mean the equivalent of the latex \mathcal{M}   )

I tried

P1:=densityplot(prova, a=0.16..0.25,b= 4..100,
grid=[25,25],   labels=["eta","M"], colourstyle=HUE,axes=box):

 

but in this way maple simply print eta (not the letter eta), If I leave the "" maple chose a like label (like the help page says).

Hi:

I'm a student majoring in Finance, and recentlly I am learning Maple.

But I found a question that I don't know how to deal with:

When learning Econometrics, and sometimes other subjects, we need to simplify a eq. like (X'*X)*b=X'*Y, where X,b,Y are Matrixes and we need to solve b.  And the kind  like that.

i'm working on a solution for the homicidal chauffeur algorithm. the data i have is two points: P (erson) and L (imo) both existing on the cartesian plane. although i think i'm doing it wrong (i'm not using diff equ's), i have a loop which runs over however many iterations it takes for the limo to come within 5 units of the person (most of the time it's taken ~100 iterations). the loop prints a bunch of data over each iteration which can easily be saved into a 4 x iterations array.

Hi there,

Here's an example maple file with my problem:

f := a*b;
B[1] := a;
B[2] := b;

when I try...

sum((diff(f, B[j]))^2, j = 1 .. 2);

I just get the answer of zero instead of b+a.

Any idea why this is happening and how I might be able to fix it?

I am trying to integrate an equation that has a cos(x), sin(x), cosh(x), sinh(x).  When I enter the equation in Maple and try to integrate the equation Maple just rewrites the equation without actually solving the equation.  I am not sure if I have to load a specific package to complete the integration.  Here is the equation:

H:= (cos(n*L)=cosh(n*L))/(sin(n*L)-sinh(n*L))

phi:=sin(n*x)-sinh(n*x)+H*(cos(n*x)-cosh(n*x)) 

when I write: int(phi(x), x=0..L)

Hi

I'm currently working on modelling a system for a design project, and I would like to incorporate my sensor's precision. If I wanted to measure an angle, but only to a precision of say, 0.3 degrees, would I have to build a custom component or is there some clever way to do this?

Thanks.
