  • 1) Sin2x d2y/dx2=2y
  • 2) a d2y/dx2= [1+(dy/dx)2]1/2
  • 3) x2 d2y/dx2-(x2+2x)dy/dx+(x+2y)y=x2ex
  • 4) d2y/dx2+2/x dy/dx=n2y

Please make sure we can tell what the problem means; for example, is Sin2x supposed to be sin(2x) or sin^2(x)? And I have no idea what "n2y" means. An image of the actual problem would be a good idea.

Also, show us where you need help. That means showing your work as far as you can get, or asking specific questions.
 
Now please show your work or ask specific questions, as I asked and as we ask here:
