\frac{d}{d x} (5 sec (5 x) tan (5 x))

5 (5 tan^{2} (5 x) sec (5 x) + 5 sec^{3} (5 x))

Solution steps

\frac{d}{d x} (5 sec (5 x) tan (5 x))

Take the constant out:

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

= 5 \frac{d}{d x} (sec (5 x) tan (5 x))

Apply the Product Rule:

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

f = sec (5 x), g = tan (5 x)

= 5 (\frac{d}{d x} (sec (5 x)) tan (5 x) + \frac{d}{d x} (tan (5 x)) sec (5 x))

\frac{d}{d x} (sec (5 x)) = sec (5 x) tan (5 x) \cdot 5

\frac{d}{d x} (tan (5 x)) = sec^{2} (5 x) \cdot 5

= 5 (sec (5 x) tan (5 x) \cdot 5 tan (5 x) + sec^{2} (5 x) \cdot 5 sec (5 x))

Simplify

5 (sec (5 x) tan (5 x) \cdot 5 tan (5 x) + sec^{2} (5 x) \cdot 5 sec (5 x)) : 5 (5 tan^{2} (5 x) sec (5 x) + 5 sec^{3} (5 x))

= 5 (5 tan^{2} (5 x) sec (5 x) + 5 sec^{3} (5 x))
