Answer 1

Answer:

Bla Bla Bla Bla Bla Bla Bla

Answer 2

Answer:

(sinx+cosx)dy+(cosx-sinx)dx=0

(sinx+cosx)dy=(sinx-cosx)dx

dy/dx=sinx-cosx/sinx+cosx

Put sinx+cosx=t

Then (cosx-sinx)dx=dt

Now

dy/dx=-dt/t

Integration on both sides we got

Y=-lnt

Y=-ln(sinx+cosx) +C ANSWER

Where C is integration constan
