\frac{d}{d x} (\frac{2}{cos ( x )})

2 sec (x) tan (x)

Solution steps

\frac{d}{d x} (\frac{2}{cos ( x )})

Simplify

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

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

Take the constant out:

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

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

Apply the common derivative:

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

= 2 sec (x) tan (x)

\frac{d}{d x} (1 0^{x} + 10 x)

\int_{\frac{π}{2}}^{π} sin (2 x) d x

\frac{sin ( x ) - x}{x ^{2}}

x \to 0 lim (sin (\frac{1}{∣ x ∣}))

\frac{3 x ^{2}}{4}
