hi freindzz,
m having a gr8 trouble in solving these questions..actually m not dat gud in Integration( I thought i was)...newayz help me in solving or atleast gimme the hint how to solve it..
Solve the Exact Differential Equations:
1) ( 1 + lnx + y/x) dx + ( cosx + xcosy)dy = 0
2) {( 1/x + 1/(x^2 )- y/[(x^2)+(y^2)]}dx + { y(e^2) + x /[( x^2)+(y^2)]}dy = 0
Can any expert of differential equations solve these difficult questions??...
I know the methology its:
1st condition > ∂M/∂y=∂N/∂x
2nd condition > ∂f/∂x=M , ∂f/∂y=N
but cant solve these question...It is a challenge for all out there..if u can do it!.
waiting for a response,
susi
