derivative of (x^2+1)^{1/2}-1

Solution

derivative of

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

Solution

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

Solution steps

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

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

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

\frac{d}{d x} (1) = 0

= \frac{x}{( x ^{2} + 1 ) ^{\frac{1}{2}}} - 0

Simplify

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