Dy=tan^(-1)((1-cos x)/(sin x))|=

tan^(-1)((cos x)/(1+sin x))

tan^(-1)((cos x)/(1-sin x))

Let y=tan ^(-1)((1-cos x)/(sin x)) i) Express 1-cos x and sinx in terms of sin (x/2) and cos (x/2) ii) Hence find (dy/dx) .

If y=tan^(-1)((1+cos x)/(sin x)),then(dy)/(dx)=

If y = tan^(-1) ((1 - cos x)/(sin x)) " then "(dy)/(dx)= ?

Find (dy)/(dx) for y=tan^(-1){(1-cos x)/(sin x)},-pi

If y=tan^(-1) ((cos x)/(1-sin x)),"then " dy/dx=
