`(d)/(dx)(xtan(x/2))=(x+sin x)/(1+cos x)`

d/(dx) (sin x+ cos x)

(d)/(dx)[(sin x)/(1+cos x)]=

(d) / (dx) (sin x) / (sqrt (1 + cos x))

(d)/(dx)(cos (x/2))= (A) (1)/(2)sin(x)/(2) , (B) -(1)/(2)cos(x)/(2) (C) -(1)/(2)sin(x)/(2) , (D) -sin(x)/(4)

(d)/(dx)[(1+cos2x+sin2x)/(1+sin2x-cos2x)]=

Differentiate the following (e^(x))/(1+sin x) and (x+sin x)/(x+cos x)

(d)/(dx)(sin^(2)x+cos^(2)x) =

differentiate (sin x)/(1+cos x)

(d) / (dx) [sin ^ (- 1) ((sin a cos x) / (1-sin a cos x))] =

(d)/(dx)[3(sin^(2)x+cos^(2)x)]=
