Transcribed Image Text:The equation
(2ye2 -8) dæ + (e²" (2x + 3y²))dy = 0
in differential form M dx + N dy = 0 is not exact. Indeed, we have
My- N2
I
For this exercise we can find an integrating factor which is a function of x alone since
M,- N2
can be considered as a function of a alone.
Namely we have µ(x)
Multiplying the original equation by the integrating factor we obtain a new equation
M da + N dy = 0 where
%3D
M =
N =
Which is exact since
My

Transcribed Image Text:Multiplying the original equation by the integrating factor we obtain a new equation
