# Find general solution for differential equation watch

1. Sin(y)cos(x) dy/dx = (x)cos(y)/cos(x)

Here is my working out so far:

2. (Original post by TSRforum)
Sin(y)cos(x) dy/dx = (x)cos(y)/cos(x)

Here is my working out so far:

integration by parts in the RHS
3. What about cos(y)sin(2x) dy/dx = cot(x)cosec(y) ? I got sin(y)cos(y) dy = 1/2cosecx^2 dx is this correct? I cant seem to integrate the dy part
