tangent of (8x+9)^{-2}

tangent of

(8 x + 9)^{- 2}

y = - \frac{16}{( 8 a _{0} + 9 ) ^{3}} x + \frac{24 a _{0} + 9}{( 8 a _{0} + 9 ) ^{3}}

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, \frac{1}{( 8 a _{0} + 9 ) ^{2}})

Find the slope of

y = (8 x + 9)^{- 2} : \frac{d y}{d x} = - \frac{16}{( 8 x + 9 ) ^{3}}

Compute the slope of

y = (8 x + 9)^{- 2}

x = a_{0} : m = - \frac{16}{( 8 a _{0} + 9 ) ^{3}}

Find the line with slope m=

- \frac{16}{( 8 a _{0} + 9 ) ^{3}}

and passing through

(a_{0}, \frac{1}{( 8 a _{0} + 9 ) ^{2}}) : y = - \frac{16}{( 8 a _{0} + 9 ) ^{3}} x + \frac{24 a _{0} + 9}{( 8 a _{0} + 9 ) ^{3}}

y = - \frac{16}{( 8 a _{0} + 9 ) ^{3}} x + \frac{24 a _{0} + 9}{( 8 a _{0} + 9 ) ^{3}}

\frac{d}{d x} (x^{3} - 12 x)

\int \frac{8 ( x ^{2} + 4 )}{x ( x ^{2} + 8 )} d x

\frac{d}{d x} (5 x^{3} + 3 x^{2} - 4 x + 1)

x \to 7 + lim (\frac{1}{x - 7})

\int e^{2 x + 4} d x
