As an intermediate result in a longer calculation I got the following equation:

Please write a code for the prolem:

Find the all values of paramater m for which the equation

I'm working on a project that involves solving a large system of polynomial equations using 'solve', with some inequalities of the form "a<>b" or "a<>0". Initially, I was using Maple 9.5 with great success; the machine I was using was upgraded to Maple 11, and now 'solve' struggles with problems that were previously easy (<30 seconds).

Were there any major changes in 'solve' between these two versions? (No, according to the documentation; Yes, according to the source....

I'am simulating a Simple AC-DC converter withTransistor NPN. When the load is just a resistance. It work. But, when I add an inductor of 10 mH to the load. Do not work. Why ?

Thanks in advance

what should do?

i guess to use Hn directly and use sum(Hn*z^m/m!)

is it possible in Maple?

Hi,

I have a third order system with nonconstant coefficients I would like to solve in Maple.  I have found a solution  but, I need a general solution.  I have attached the worksheet.  In the worksheet I have commented the system and the known solution.  AllCalculationsPertu.mw

Is there some way to construct the general solution from known solutions like a variation of parameters?

Today I found that login does not work on MaplePrimes.  I changed my password, but still not.

There is no error, I am just returned to the provious page, still not logged in.

How to patch library maple functions locally if there any method?

Found that in

IntegralTransforms:-Tools:-SimplifyPower

in 195-196

instead of

j := evalf(j[-1][2]-1);
k := evalf(j[1][1]+1)

should be

j := evalf(t1[-1][2]-1);
k := evalf(t1[1][1]+1)

How to update maple?

How to convert Kummer expression into other simple formula?

i have calculated a generating function, but the actual answer is much simpler than this

Gen := {p(z) = exp(-I*z/sqrt(c))*KummerM(-(-(1/2)*sqrt(c)*beta+(1/2*I)*beta*c+I*(-1/2+c)*x)/sqrt(c),
beta,

Hi

Sorry for this noobish question but I have problems solving this 2-dimensional Integral:

int(x*y(x^2-y^2)/(3*(x^2+y^2)^3), [x = 0 .. 2, y = 0 .. 1])

Maple 14 does not solve it. Mathematica did solve it but I was hoping for Maples Integration tutor (great thing) to help me solve this on my own.

Thanks

Hi,

Im not sure if anyone can help but whenever I plot a graph maple freezes. It looks like the program just refuses to plot it and repeats the command until i get to past where the graph should be at which time it goes back to working fine.

Another way of describing the error is, whenever i...

rsolve({c*(n+beta)*P(n+1)/(-1+c)+(c*(x+beta)/(1-c)-x)*P(n)+n*P(n-1)/(-1+c)=0,P(0)=1}, P(n));
return rsolve({c*(n+beta)*P(n+1)/(-1+c)+(c*(x+beta)/(1-c)-x)*P(n)+n*P(n-1)/(-1+c)=0,P(0)=1}, P(n));

Any other method besides rsolve to solve genfun?

i discover it can solve variable coefficient and n coefficient too.

but sometimes n*P(n+1) make it can not solve, i have to remove n to P(n+1)

any paper describing the mechanism of rsolve, where it store the maple code of rsolve in maple 15?
