Maple da differensial tenglamalar

> deq5:=diff(y(t),t)-t^2*y(t)=sin(t);



> dsolve(deq5,y(t) );



Quyida berilgan birinchi tartibli differensial tenglamaning umuiy yechimi topilgan (uni Maple oshkor ko‘rinishda aniqlagan). So‘ngra oshkormas (implicit) ko‘rinishdagi yechim topilib, unga ko‘ra plots paketining contourplot buyrug‘i yordamida 6 ta yechim grafigi qurilgan.

> with(plots): deq:=diff(y(x),x)+x^2/y(x)=0;yech_oshkor:=dsolve(deq,y(x));
yech_oshkormas:=dsolve(deq,y(x),implicit);
F:=subs({y(x)=y,_C1=0},lhs(yech_oshkormas));
contourplot(F,x=-8..8,y=-12..12,color=black,contours=6, thickness=2);
