# rRr0 = (dy / dx) e ^ y- (cosxy + x (-yysxy-x (dy) / dx (sinxy))) #

# rRr0 = (dy / dx) e ^ y- (cosxy-xysinxy-x ^ 2 (dy) / dx (sinxy)) #

# rRr0 = (dy / dx) e ^ y-cosxy + xysinxy + x ^ 2 (dy) / dx (sinxy) #

# rRr0 = (dy / dx) e ^ y + x ^ 2 (dy) / dx (sinxy) -cosxy + xysinxy #

# rRr0 = (dy / dx) (e ^ y + x ^ 2 (sinxy)) - cosxy + xysinxy #

# rRrccosxy-xysinxy = (dy / dx) (e ^ y + x ^ 2 (sinxy)) #
