derivative of

4 sec (x) tan (x)

4 (- sec (x) + 2 sec^{3} (x))

Solution steps

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

Take the constant out:

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

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

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = sec (x), g = tan (x)

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

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

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

= 4 (sec (x) tan (x) tan (x) + sec^{2} (x) sec (x))

Simplify

4 (sec (x) tan (x) tan (x) + sec^{2} (x) sec (x)) : 4 (- sec (x) + 2 sec^{3} (x))

= 4 (- sec (x) + 2 sec^{3} (x))

y^{^{'}} = 3 x + y, y (0) = 3

\frac{d}{d x} (3 x sin (2 x))

\frac{1}{4 - x ^{2}}

\int (2 sin (t) cos (t)) d t

x \to 0 + lim (\frac{cos ( x )}{x})
