Hello, this is the first time I post here, I'm really stumped and tried everything, even my TI-89 calculator won't give me something nice XD 1. The problem statement, all variables and given/known data Find the general solution of dy/dt= 1/(ty+t+y+1) 2. Relevant equations No relevant equations. 3. The attempt at a solution The first step I did was, (ty+t+y+1)dy = 1dt by cross multiplying proportions. I can't figure out anyway to seperate my terms to the proper places...I then tried this: integral( ty+t+y+1 dy ) = integral( 1dt ) and resulted in: ty^2/2 + ty + y^/2 + y + c = t But this leads me nowhere...Any ideas? Or should I come into conclusion that this differential equation is not valid and unable to do?
