derivative of

\frac{3}{cos ( x )}

3 sec (x) tan (x)

Solution steps

\frac{d}{d x} (\frac{3}{cos ( x )})

Simplify

\frac{3}{cos ( x )} : 3 sec (x)

= \frac{d}{d x} (3 sec (x))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 3 \frac{d}{d x} (sec (x))

Apply the common derivative:

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

= 3 sec (x) tan (x)

2 x (1 + 3 x^{2})^{3}

y = (2 x + 1)^{5}

(4 - 3 x^{2})^{5}

g (z) = 10 tan (z) - 2 cot (z)

\frac{d}{d t} (t^{5} + 3 t^{- 2} + sin (t))
