Vastaus:

#f '(x) = - s ^ 2xsin (tanx) cos (cos (tanx)) #

Selitys:

#f (x) = sin (g (x)) #

#f '(x) = g' (x) cos (g (x)) #

#G (x) = cos (h (x)) #

#G '(x) = - h (x) sin (h (x)) #

#h (x) = tan (x) #

#h '(x) = s ^ 2x #

#G '(x) = - s ^ 2xsin (tanx) #

#G (x) = cos (tanx) #

#f '(x) = - s ^ 2xsin (tanx) cos (cos (tanx)) #
