\frac{d}{d x} (tan^{4} (3 x))

12 tan^{3} (3 x) sec^{2} (3 x)

Solution steps

\frac{d}{d x} (tan^{4} (3 x))

Apply the chain rule:

4 (tan (3 x))^{3} \frac{d}{d x} (tan (3 x))

= 4 (tan (3 x))^{3} \frac{d}{d x} (tan (3 x))

\frac{d}{d x} (tan (3 x)) = sec^{2} (3 x) \cdot 3

= 4 (tan (3 x))^{3} sec^{2} (3 x) \cdot 3

Simplify

= 12 tan^{3} (3 x) sec^{2} (3 x)
