Here is my riposte (not OC)

>>9154041
how can you call that shit a DE it's almost a direct integral

1.) Naturally, if r depends on m, dy/dx=(1/r)sin^2m dr/dm. Hence, the equation becomes r (sinm + cosm)(1/r)sin^2mdr/dm=r (sinm-cosm).

Thus dr/dm=r*(sinm-cosm)/(sin^2m (sinm+cosm))=-r. Then dr/dm+r=0.

2.) The equation can be rewritten as -x (x^2+y^2)dy/dx=-y(x^2+y^2) since the rest of the equation is equal to zero as per 1.). This becomes cosmsin^2mdr/dm=rsinm which then becomes cosm sinm dr/dm=r.

The equation becomes ln r= 2int csc2m. I don't know how they're getting the equation specified on the problem from this.

I may just be tired, but I kek'd pretty hard.

Just square the equation first then go from there, friend.
