x'=xy
y'=4x+y
solver these both
the first equation can be seprated and end up with ln|x|=(y^2)/2 but then if you solve for y and try to plug into the second equation you get somethin ugly:
y'=4x+sqrt(2ln|x|)
or if you try to find roots you get somethin even uglier y"=4e^(y^2/2)+y
im at a lose at how to do this, can anyone hlep me.
thanks in advance
