I recently had a journal article accepted but was told that several of the graphs had to be redone because the axes were not thick enough to reproduce. Unfortunately, Maple has no way to edit the axes for thickness, so I had to export the differential equations to Matlab and integrate them there to get publication quality graphs. I have been having more trouble every year with the quality of Maple's graphics output, and this really puts a cherry on it. I would be pleased as punch if Maple could include a graph editor that would let us customize a graph to make it presentable to publishers. Maple does so many things so well it is a shame to leave this on the back burner.

In next procedure i calculated 1st derivative of H in y=0 via series approximation. And i see that some terms of series are missed. If i would raise second parameter to cnt+20 for FuncToSeries in GetLimitsArray it becomes better. But why it's not OK with even cnt+8? series_test.mw

I have the numerical solution of Phi(r,t) which is a numerical solution of a pde..

I want to find the following energy integral at fixed time say t=10 ,

Energy = int(a*r^2*Phi(r,10)^2 + 2*b*r*Phi(r,10)^3,r=0..infinity)... I could not find help in maple.. I guess I had to do the following

 

1. select the numerical solution dependent only on r at t=10 slice..

2.Use numerical methods to evaluate the integral..

 

Just try simplify :

to_zero.mw

with(Statistics):
Phiinverse := (x) -> Quantile(Normal(0, 1), x) :

evalf(Phiinverse(1-1/2^24));

and the result is 5.691523310-2.147372008*I

Now, I can get a real-valued solution to this by using the equivalent
functionality from stats instead of Statistics.

with(stats):
PhiinvClassic:= (x) -> statevalf[icdf, normald[0, 1]](x):

evalf(PhiinvClassic(1-1/2^24));

I have coded maple script and got that error. How can I fix it?

Here is my code error.mw. Please help.

Thanks

Hi.

I have two complex functions with 3 variables: z1,z2,t . I need the first derivative of one of these functions with respect to one variable onle. Here is what I did:

f1:=z1(t)+2*z2(t):

f2:=z1(t)-3*z2(t):

diff(f1,z1(t)) this gives me an error. I need to write the variable as z1(t) not z1 because I'm doing some calculations for different time.

Thanks for the help.

Hello,

     I just purchased Maple and I am just learning calculus pretty much for fun.  I am reading "Calculus Made Easy" by Sylvanus Thompson.  On page 56 there is a set of equations for which I would like to know the steps.  I was wondering how to do this in Maple.  I played around with the Student and Tutor commands, but can't seem to get it to work.

     The equation is y+dy=(x+dx)^-2

hi,

how to change coordinate system? 

for example :

diff(f(x, y), x)   =   (diff(f(r, theta), r))*cos(theta)-(diff(f(r, theta), theta))*sin(theta)/r

 

thx;

aryan.

 

I am going to use maple in connection with my project concerning non-linear dynamic and chaos, but i have never used the program before, so I hope you guys can help me with that,

I have a model of non-linear dynamic system as following:

dA/dr = k + m * Y(r) - A(r) * B(r) * B(r) - A(r)

dB/dr=1/q * [A(r) * B(r) * B(r) + A(r) - B(r)]

dY/dr=1/s * [B(r) - Y(r)] 

the values of the parameters are:
k= 10
q= 5 * 10^(-3)
s=2 * 10^(-2)

well first of all this site was very useful for doing my homework, but there is still something I didnt find on it and im sure other people may find it useful.

 

I have a system of 5 ode's and 6 initial conditions that ive solved successfully and plotted the graphs i need:  Position VS Time

          Speed VS Time

The only thing I initially know is the final position, which i can read on the first graph and...

I've found no questions about these types of functions. When I try to solve this equation by using the FOC function and then try to isolate one of the variables 'effort' (or optimal effort) the outcome is about 6 lines of algebra. When I use simplify it expands even further. What other options are there to get a 'nice' expression?

Professor is working in Maple 13  I have Maple 15 just started using this. 

He types 

DE1:=diff(TS(t),t)=3*k[abs]*IO*f/4/r[O]/c[W]/rho[O]-mu*T[O]/(s+1)/r[O]^2/C[W]/rho[O]*((Ts(t)/T[O]^(s+1)-1);

I can not type the math in this format in Maple 15. Can anyone help me, I keep getting error messages.

 

Thanks

The Standard GUI has an option (Tools -> Options -> General -> Browser) for configuring an installed web browser.  The GUI uses that for its own purposes (for example, clicking on an error message opens the browser at a related Maplesoft site).  Is it possible for the user to access the configured web browser from within Maple, using Maple code?
