Best ResponseYou've already chosen the best response.1sin(x+y)=xy or, cos(x+y) . [ 1+ dy/dx ] = x dy/dx + y

Best ResponseYou've already chosen the best response.0I dont know what to do from here exactly in cos(x+y) [1+dy/dx]= x dy/dx + y

Best ResponseYou've already chosen the best response.1or, cos(x+y) + cos(x+y) dy/dx = x dy/dx + y or, cos(x+y) dy/dx  x dy/dx = y  cos(x+y) or, dy/dx {cos(x+y)  x} = y  cos(x+y) or, dy/dx = [ y  cos(x+y) ] / [ cos(x+y)  x ].................. Ans.

Best ResponseYou've already chosen the best response.1Yes the Last one [ y  cos(x+y) ] / [ cos(x+y)  x ] is the answer :)
