\frac{d}{d x} (\frac{5}{x + 8})

- \frac{5}{( x + 8 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{5}{x + 8})

Take the constant out:

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

= 5 \frac{d}{d x} (\frac{1}{x + 8})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= 5 \frac{d}{d x} ((x + 8)^{- 1})

Apply the chain rule:

- \frac{1}{( x + 8 ) ^{2}} \frac{d}{d x} (x + 8)

= - \frac{1}{( x + 8 ) ^{2}} \frac{d}{d x} (x + 8)

\frac{d}{d x} (x + 8) = 1

= 5 (- \frac{1}{( x + 8 ) ^{2}} \cdot 1)

Simplify

5 (- \frac{1}{( x + 8 ) ^{2}} \cdot 1) : - \frac{5}{( x + 8 ) ^{2}}

= - \frac{5}{( x + 8 ) ^{2}}

y = 3 x, y = \frac{3}{x}, x = 4

\int - sin (\frac{1}{2} x) d x

f (x) = 6 cos (x)

\int \frac{tan ^{2} ( x )}{cos ^{2} ( x )} d x

f (x) = 3 x^{3}, (- 1, - 3)
