Question

Can someone help me derivative this ?
Y=(1-sin x / 1+sin x)^3

Answer 1

its so simple...in this example we are gonna find dy/dx so proceed as i say assume (1-sinx/1+sinx) =z then you will get y=z^3 .. now you have on when you derivate this you will get dy/dz =3z^2 but remember we want dy/dx so mulitiply the result dy/dz by dz/dx that mulitiply the result dy/dz by derivative of with respect to x.. if you didnt get this.. ask for more explanation.. :)
