Answered by Anonymous286

Steps:
1) Basically divide numerator and denominator by cos x
2)you would get 1-tanx/1+tanx inside tan inverse
3) write the 1 in numerator as tan(π/4)
4)So you would get the formula of tan(π/4-x) inside tan inverse
5)Now tan^-1[tan(π/4-x)]
6)So π/4-x
Now take derivative
answer is -1
HOPE IT HELPS
