Hello! Currently I own Differential Equations by H.B Phillips, a really old book, but difficult and does it´s purpose. I have only 1 problem, certain exercises require certain geometrical functional study I suppose, for example:
"find the equation of the curves so that the part of every tangent between the y-axis and the tangent point P(x,y) is divided in 2 equal parts by the x-axis." (sorry if I translated wrong)
To be honest, I hesitated a bit trying to find such a curve, so I checked the answers, and it was a simple quadratic equation, therefore I realized I need to study a bit geometry of functions, so if someone can recommend a book I would thank him a lot.
