\frac{d}{d x} (tan (7 x))

\frac{7 sec ^{2} ( 7 x )}{2 x}

Solution steps

\frac{d}{d x} (tan (7 x))

Simplify

tan (7 x) : tan (7 x)

= \frac{d}{d x} (tan (7 x))

Apply the chain rule:

sec^{2} (7 x) \frac{d}{d x} (7 x)

= sec^{2} (7 x) \frac{d}{d x} (7 x)

\frac{d}{d x} (7 x) = \frac{7}{2 x}

= sec^{2} (7 x) \frac{7}{2 x}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{7 sec ^{2} ( 7 x )}{2 x}
