derivative of arcsec(x^2+1)

Solution

\frac{d}{d x} (arcsec (x^{2} + 1))

Solution

\frac{2}{( x ^{2} + 1 ) x ^{2} + 2}

Solution steps

\frac{d}{d x} (arcsec (x^{2} + 1))

Apply the chain rule:

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

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

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

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

Simplify

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

= \frac{2}{( x ^{2} + 1 ) x ^{2} + 2}
