\frac{d}{d x} (\frac{4}{cos ( x )})

4 sec (x) tan (x)

Solution steps

\frac{d}{d x} (\frac{4}{cos ( x )})

Simplify

\frac{4}{cos ( x )} : 4 sec (x)

= \frac{d}{d x} (4 sec (x))

Take the constant out:

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

= 4 \frac{d}{d x} (sec (x))

Apply the common derivative:

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

= 4 sec (x) tan (x)

\int - \frac{3}{25} x + 49 d x

\frac{\partial}{\partial z} (2 y)

e (t)

x \to 1 lim (\frac{x - 2}{∣ x - 1 ∣})

y = x^{4} + 3 x^{2} - x, (1, 3)
