回答:

#dy / dx =(ycos(xy))/(1-xcos(xy))#

说明:

我们得到了使用隐式差异,产品规则和链规则

#d / dxy = d / dxsin(xy)#

#=> dy / dx = cos(xy)(d / dx(xy))#

#= COS(XY)X(d / DXY)+ Y(d / DXX)#

#= cos(xy)(xdy / dx + y)#

#= xcos(xy)dy / dx + ycos(xy)#

#=> dy / dx - xcos(xy)dy / dx = ycos(xy)#

#=> dy / dx(1-xcos(xy))= ycos(xy)#

#:. dy / dx =(ycos(xy))/(1-xcos(xy))#
