Hey its simple dy/dx = Ae^x A = dy/dx / e^x Substituting back in 1st equation y = dy/dx / e^x * e^x + b d^2 y/ dx^2 = dy/dx That is the differential equation. Cheers!

y=Aex+B dy/dx=Aex So A=(dy/dx)/ex d2y/dx2=Aex d2y/dx2=dy/dx So the required diffrential equation is d2y/dx2-dy/dx=0

That is ok if u want to form differential equation with this. but still i feel question is not clear as it doesn't mention what it requires.

The Scientist does not study nature because it is useful; he studies it because he delights in it, & he delights in it because it is beautiful. If nature were not beautiful, it would not be worth knowing, life would not be worth living. Ofcourse I do not here speak of that beauty that strikes the senses, the beauty of qualities & appearances; not that I undervalue such beauty, far from it, but it has nothing to do with science; I mean that profounder beauty which comes from the harmoniuos order of the parts, & which a pure intelligence can grasp. |

I agree with edision... but you have given the subject "diffrential equ".. and if you want to find the diff eqn for the given expression..you have already got the ans.

is diff equ d^2y/dx^2=dy/dx even dy/dx=y is also possible????????
