derivative of

lo g_{10} (x^{2} + a^{2})

\frac{2 x}{ln ( 10 ) ( x ^{2} + a ^{2} )}

Solution steps

\frac{d}{d x} (lo g_{10} (x^{2} + a^{2}))

Apply log rule:

lo g_{a} (b) = \frac{ln ( b )}{ln ( a )}

= \frac{d}{d x} (\frac{ln ( x ^{2} + a ^{2} )}{ln ( 10 )})

Take the constant out:

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

= \frac{1}{ln ( 10 )} \frac{d}{d x} (ln (x^{2} + a^{2}))

Apply the chain rule:

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

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

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

= \frac{1}{ln ( 10 )} \cdot \frac{1}{x ^{2} + a ^{2}} \cdot 2 x

Simplify

\frac{1}{ln ( 10 )} \cdot \frac{1}{x ^{2} + a ^{2}} \cdot 2 x : \frac{2 x}{ln ( 10 ) ( x ^{2} + a ^{2} )}

= \frac{2 x}{ln ( 10 ) ( x ^{2} + a ^{2} )}

x^{2} sec (x)

x \cdot sin (3 y) + x \cdot e^{\frac{y}{x}}

(\frac{x + 1}{x ^{2} + 3}) - 3

\frac{d}{d y} (3 - y^{2})

(x^{6} + 3 x^{2} - x + 3)^{^{'}}
