回答:
#(dy)/ dx =(cosxy-xysinxy)/(e ^ y + x ^ 2(sinxy))#
説明:
#1 = e ^ y - xcos(xy)#
#rArr(d1)/ dx = d / dx(e ^ y - xcos(xy))#
#rArr0 =(de ^ y)/ dx-(d(xcos(xy)))/ dx#
#rArr0 =(dy / dx)e ^ y - (((dx)/ dx)cosxy + x(dcosxy)/ dx)#
#rArr0 =(dy / dx)e ^ y-(cosxy + x(dxy)/ dx(-sinxy))#
#rArr0 =(dy / dx)e ^ y-(cosxy + x((y + x(dy)/ dx)( - sinxy)))#
#rArr0 =(dy / dx)e ^ y-(cosxy + x(-ysinxy-x(dy)/ dx(sinxy)))#
#rArr0 =(dy / dx)e ^ y-(cosxy-xysinxy-x ^ 2(dy)/ dx(sinxy))#
#rArr0 =(dy / dx)e ^ y-cosxy + xysinxy + x ^ 2(dy)/ dx(sinxy)#
#rArr0 =(dy / dx)e ^ y + x ^ 2(dy)/ dx(sinxy) - cos + xysinxy#
#rArr0 =(dy / dx)(e ^ y + x ^ 2(sinxy)) - cosxy + xysinxy#
#rArrcosxy-xysinxy =(dy / dx)(e ^ y + x ^ 2(sinxy))#
#rArr(dy)/ dx =(cosxy-xysinxy)/(e ^ y + x ^ 2(sinxy))#
