1.(D^(4)+2a^(2)D^(2)+a^(4))y= 8 cos ax
2.(d^(2))/(dx^(2))+(3dy)/(dx)+2y=sin2x
3.(d^(2)y)/(dx^(2))+y=sin3xcos2x
I need solution above those math,can anybody help me

If all physical things are made of atoms then why do different physical things have different physical properties? Like why sodium is soft and diamond is hard?
