(1) will write us of the following form


(dy)/(dx)+y^2\sin x=0\\ \\

(2) [do not it need explanation]


(dy)/(dx)=-y^2\sin x\\ \\

(3) Left place variable "y" and right place, variable "x" like this


(dy)/(y^2)=-\sin x\, dx\\ \\

(4) Integrate both members


\displaystyle \int (dy)/(y^2)=\int-\sin x\, dx\\ \\

(5) Solve us the integrals


-(1)/(y)= \cos x+C

(6) Isolate variable "y"


\boxed{y=-(1)/(\cos x+C)}

C: any cosntant
