How can I change the output format of the desolve command ?
On on iPad, with PocketCas, the output of desolve(y''+1/(x+1)=0,x,y) is -ln(x+1)+x-x*ln(x+1)+c0*x+c1

On the Prime I get ilaplace((e^_t38*Ei(-_t38)/_t38^2 _t38 x))+G_1*x+G_0

Indeed, it should not use the laplace transform to solve this one, fixed in giac.
