derivative of

tan (x) - 1

sec^{2} (x)

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

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

= sec^{2} (x) - 0

Simplify

= sec^{2} (x)
