ankoles [38]

Answer:

let M=ex +y and N=2 +x +yey

(a) σM/σy =1 and σN/σx = 1

since σM/σy = σN/σx , it is an exact equation

(b) ∫M dx + ∫terms of N not containing x

∫(ex + y) dx +∫yey + 2 dy

xy + ex +yey -ey +2y=C

C=3

(d) from the differential equation given

by dividing through by dx

dy/dx = (-y-ex) /(2+x+yey)

from the solution

$\frac{d}{dx}$ (xy + ex +yey -ey =2y)= $\frac{d}{dx}$ (3)

x $\frac{dx}{dy}$ + y + ex + yey $\frac{dy}{dx}$ + ey $\frac{dx}{dy}$ - ey $\frac{dy}{dx}$ + 2 $\frac{dy}{dx}$ = 0

$\frac{dy}{dx}$ = (-y-ex) /(2+x+yey)

Step-by-step explanation:

1. integrate with respect to x keeping y constant

2. integrate terms without x in N

3. Result of 1 + result 2= C

4. insert the condition given into 3

5. compare the solution of 4 to the differential equation
