\frac{d}{d x} (10 sec (2 x) tan (2 x))

10 (2 tan^{2} (2 x) sec (2 x) + 2 sec^{3} (2 x))

Solution steps

\frac{d}{d x} (10 sec (2 x) tan (2 x))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 10 \frac{d}{d x} (sec (2 x) tan (2 x))

Apply the Product Rule:

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

f = sec (2 x), g = tan (2 x)

= 10 (\frac{d}{d x} (sec (2 x)) tan (2 x) + \frac{d}{d x} (tan (2 x)) sec (2 x))

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

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

= 10 (sec (2 x) tan (2 x) \cdot 2 tan (2 x) + sec^{2} (2 x) \cdot 2 sec (2 x))

Simplify

10 (sec (2 x) tan (2 x) \cdot 2 tan (2 x) + sec^{2} (2 x) \cdot 2 sec (2 x)) : 10 (2 tan^{2} (2 x) sec (2 x) + 2 sec^{3} (2 x))

= 10 (2 tan^{2} (2 x) sec (2 x) + 2 sec^{3} (2 x))
