derivative of ln(xtan(x))

Solution

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

Solution

\frac{tan ( x )}{x} + sec^{2} (x) ln (x)

Solution steps

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

Apply the Product Rule:

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

f = ln (x), g = tan (x)

= \frac{d}{d x} (ln (x)) tan (x) + \frac{d}{d x} (tan (x)) ln (x)

\frac{d}{d x} (ln (x)) = \frac{1}{x}

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

= \frac{1}{x} tan (x) + sec^{2} (x) ln (x)

\frac{1}{x} tan (x) = \frac{tan ( x )}{x}

= \frac{tan ( x )}{x} + sec^{2} (x) ln (x)
