Answer:

1/ sqrt(1+ln^2(x)) * 1/(ln^2x +1) * 1/x

Step-by-step explanation:

f(x) = sin (tan^-1 (ln(x)))

u substitution

d/du (sin u) * du /dx

cos (u) * du/dx

Let u =(tan^-1 (ln(x))) du/dx =d/dx (tan^-1 (ln(x)))

v substitution

Let v = ln x dv/dx = 1/x

d/dv (tan ^-1 v) dv/dx

1/( v^2+1) * dv/dx

=1/(ln^2x +1) * 1/x

Substituting this back in for du/dx

cos (tan^-1 (ln(x)) * 1/(ln^2x +1) * 1/x

We know that cos (tan^-1 (a)) = 1/ sqrt(1+a^2)

cos (tan^-1 (ln(x)) * 1/(ln^2x +1) * 1/x

1/ sqrt(1+ln^2(x)) * 1/(ln^2x +1) * 1/x
