derivative of f(x)=arcsec(2x)

Solution

derivative of

f (x) = arcsec (2 x)

Solution

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

Solution steps

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

Apply the chain rule:

\frac{1}{( 2 x ) ^{2} ( 2 x ) ^{2} - 1} \frac{d}{d x} (2 x)

= \frac{1}{( 2 x ) ^{2} ( 2 x ) ^{2} - 1} \frac{d}{d x} (2 x)

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

= \frac{1}{( 2 x ) ^{2} ( 2 x ) ^{2} - 1} \cdot 2

Simplify

\frac{1}{( 2 x ) ^{2} ( 2 x ) ^{2} - 1} \cdot 2 : \frac{1}{x ^{2} 4 x ^{2} - 1}

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