# Thread: differential sec x dy/dx = y^2

1. ## differential sec x dy/dx = y^2

can some help me on how to tackle this.

does sec x = 1/cos x?

Yes and I believe this is a separable Non Linear ODE..ie rearrange to put all your x's one one side and y's on the other and then integrate.

3. i have rearranged, but struggling with integrating both sides.

4. I think you have a division error in there. I think it should be

What does that give you when you integrate?

5. is this the solution?

6. oh almost forgot.....do i add a constant to both sides?

7. You could get away with one constant because subtracting a constant from another constant will leave you with a constant
