derivative of

\frac{1}{cos ( x )}

\frac{sec ( x ) tan ( x ) cos ( x )}{2}

Solution steps

\frac{d}{d x} (\frac{1}{cos ( x )})

Apply the chain rule:

\frac{1}{2 \frac{1}{c o s ( x )}} \frac{d}{d x} (\frac{1}{cos ( x )})

= \frac{1}{2 \frac{1}{c o s ( x )}} \frac{d}{d x} (\frac{1}{cos ( x )})

\frac{d}{d x} (\frac{1}{cos ( x )}) = sec (x) tan (x)

= \frac{1}{2 \frac{1}{c o s ( x )}} sec (x) tan (x)

Simplify

\frac{1}{2 \frac{1}{c o s ( x )}} sec (x) tan (x) : \frac{sec ( x ) tan ( x ) cos ( x )}{2}

= \frac{sec ( x ) tan ( x ) cos ( x )}{2}

\int \frac{e ^{8 t}}{t} d t

\frac{1}{s ^{2} + 0.5 s + 1}

x \to 1 lim ((x - 1)^{l n (x)})

t \to - 2 lim (\frac{t ^{4} - 8}{2 t ^{2} - 3 t + 8})

\frac{d y}{d t} - 2 t y = t
