\frac{d}{d θ} (sec (θ) \cdot tan (θ))

- sec (θ) + 2 sec^{3} (θ)

Solution steps

\frac{d}{d θ} (sec (θ) tan (θ))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = sec (θ), g = tan (θ)

= \frac{d}{d θ} (sec (θ)) tan (θ) + \frac{d}{d θ} (tan (θ)) sec (θ)

\frac{d}{d θ} (sec (θ)) = sec (θ) tan (θ)

\frac{d}{d θ} (tan (θ)) = sec^{2} (θ)

= sec (θ) tan (θ) tan (θ) + sec^{2} (θ) sec (θ)

Simplify

sec (θ) tan (θ) tan (θ) + sec^{2} (θ) sec (θ) : - sec (θ) + 2 sec^{3} (θ)

= - sec (θ) + 2 sec^{3} (θ)

\int \frac{x}{2 x} d x

\int t^{2} sin (2 t) d t

f (x) = x^{\frac{1}{4}}

x \to + \frac{π}{2} lim (tan (x))
