\frac{d}{d x} (1 - tan (x))

- sec^{2} (x)

Solution steps

\frac{d}{d x} (1 - tan (x))

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (1) - \frac{d}{d x} (tan (x))

\frac{d}{d x} (1) = 0

\frac{d}{d x} (tan (x)) = sec^{2} (x)

= 0 - sec^{2} (x)

Simplify

= - sec^{2} (x)
