You can't juggle around with differential operators the way you have. They are not common algebraic variables. So first of all, the dy's in the expression don't cancel out. d(dy/dx)/dy=(d²y/dx²)( This is the Solution of Question From RD SHARMA book of CLASS 12 CHAPTER DIFFERENTIAL EQUATIONS This Question is also available in R S AGGARWAL book of CLASS Jun 21, 2011 Nov 09, 2018 In calculus, Leibniz's notation, named in honor of the 17th-century German philosopher and mathematician Gottfried Wilhelm Leibniz, uses the symbols dx and dy to represent infinitely small (or infinitesimal) increments of x and y, respectively, just as Δx and Δy represent finite increments of x and y, respectively.. Consider y as a function of a variable x, or y = f(x).

### A simpler solution would be v=y' and then it becomes v'+v=x^2 which has an integrating factor of e^x which makes it \left (ve^x\right )'=x^2e^x and integrating both sides ve^x=e^x(x^2-2x+2)+C_1 A simpler solution would be v = y ′ and then it becomes v ′ + v = x 2 which has an integrating factor of e x which makes it ( v e x ) ′ = x 2

Now integrating both sides of the equation (i), we have. ∫ e y d y = ∫ e x d x. Using the formulas of integration ∫ e x d x = e x , we get. e y = e x + c ⇒ y = ln.
