i) In the differential equation [1-(y^2)](dy/dx)+1/y=e^(2x)
make the substitution u=1/y and hence show that the general solution to the equation is y=1/[(Ae^x)-e^(2x)].
Help would be greatly appreciated.
Note the cross partial test fails,
M_y not = N_x
Is a function only of "y" thus, you can find an integrating factor.
