Hi

I founda something strange here:

diff(y(x),x$2)+4*y(x)=cos(2*x);

dsolve(%,y(x));

 

y(x) = sin(2*x)*_C2+cos(2*x)*_C1+1/8*cos(2*x)+1/4*sin(2*x)*x

 

that's the answer maple give me when i run it for the first time

take a look at the two cos(2*x) tern?

shouldnt that be just ONE constant times it?

 

ok then if you run it again

somtimes it can collect them together give you single cos(2*x) term with ONE constant

but sometimes it just keep giving you TWO cos(2*x) terms.....

WERIED....

I am using Maple 11.02 Classical Mode on xp xp2 english version

 

Is this somekind of Maple programme problem? Personally I am interested in mathematically programme developping as well. So it brought my attenstion

Cheers
