Explanation:
#"differentiate "color(blue)"implicitly with respect to x"#
#"differentiate both sides using the "color(blue)"product rule"#
#"given "y=f(x)g(x)" then"#
#dy/dx=f(x)g'(x)+g(x)f'(x)larrcolor(blue)"product rule"#
#rArrxcosydy/dx+siny=xdy/dx+y#
#rArrxcosydy/dx-xdy/dx=y-siny#
#rArrdy/dx(xcosy-x)=y-siny#
#rArrdy/dx=(y-siny)/(xcosy-x)#
