Hello,

I am having trouble solving the 2 following problems.

Given the differential equation solve by separation of variables.

1. sec^2(x) dy + csc(y) dx =0

I have tried to get the y's on the left and the x's on the right and integrate, but I cannot get the correct solution. This is what I have so far....

1/(csc(y)) dy = 1/(sec^2(x))

But I'm just not getting 4cos(y)=2x+sin(2x)+c

2. dy/dx = (xy + 3x - y-3) / (xy - 2x + 4y -8)

On this problem I am not sure where to start.

Any help is greatly appreciated. Thanks!
