Suppose we want to find an integrating factor only dependent of then let and and see that thus is the integrating factor we want.
The integrating actor of the diferential eqn
2cos(y^2)dx - xysin(y^2) dy = 0 is
Writing in terms of dx/dy I got the anwer to be (cos(y^2))^(1/4). its not even one of the options
But in terms of dy/dx I dont know what the answer is
