## Another case...

@pagan Hi pagan, thank you for your answer and patience. I tried your code and it worked for the specific case. By the way, when I changed the code to "assuming y(0)::finite", Maple aslo worked out the result. However, I have a follow-up question on the same subject. Please refer to the following lines of code.

```restart;

dsolve({diff(y(x),x,x)+diff(y(x),x)/x-y(x)*(n^2)/(x^2)=-4*(n^2)/(x^2),y(1)=0,y(0)=y(0)})
assuming y(0)::finite;
```

Maple returned "y(x)=x^n*C1+x^(-n)(-C1-4)+4". My intention was to ask Maple to solve the ODE assuming that n was a positive integer so that C1=-4 and the coefficient in front of x^(-n) would disappear. I tried to juxtapose another condition "n::posint" along with y(0)::finite in my assumption argument, but Maple complained that no assumption can be made about n as it is a constant.

Have you any suggestions? Thank you again for your help.

## No result...

@pagan Hello, thank you all for your replies. However, I have not yet managed to obtain a result with the following codes:

```restart;
assume(K<infinity);
dsolve({diff(y(x),x,x)+(diff(y(x),x))/x+8,y(1)=0,y(0)=K});```

As you can see, I wish to specify the condition y(0) is finite when I execute dsolve. Any suggestions?
