derivative of ln(sec(x^2))

Solution

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

Solution

2 x tan (x^{2})

Solution steps

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

Apply the chain rule:

\frac{1}{sec ( x ^{2} )} \frac{d}{d x} (sec (x^{2}))

= \frac{1}{sec ( x ^{2} )} \frac{d}{d x} (sec (x^{2}))

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

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

Simplify

\frac{1}{sec ( x ^{2} )} sec (x^{2}) tan (x^{2}) \cdot 2 x : 2 x tan (x^{2})

= 2 x tan (x^{2})
