Homework Statement
solve the quation dy/dx = (4x - x^3) / (4 + y^3)
the first thing the book does is rewrite the equation as:
(4+y^3)dy = (4x-x^3)dx
and i understand that they are 1st separating it out... BUT shouldn't it be (1 / (4+y^3))dy?
How can they dissmiss the fact that the y terms are in the denominator?
On every problem, the fact that terms are under denominator gets ignored --why?
