tangent of f(x)=8x^2+8x-5,\at x=-1/2

tangent of

f (x) = 8 x^{2} + 8 x - 5, at x = - \frac{1}{2}

y = - 7

Solution steps

Find the tangent point:

(- \frac{1}{2}, - 7)

Find the slope of

f (x) = 8 x^{2} + 8 x - 5 : \frac{df ( x )}{d x} = 16 x + 8

EN : T i tl e G e n er a l Eq u a t i o n Sl o p e A t P o in t 2 Eq : m = 0

Find the line with slope m=

0

and passing through

(- \frac{1}{2}, - 7) : y = - 7

y = - 7

\frac{d}{d x} (\frac{4 x}{5 - tan ( x )})

\frac{d}{d x} (x + \frac{4}{x - 4})

t an g e n t 2 x^{2} - 8 x - 7

\int \frac{5}{8} csc^{2} (\frac{x}{8}) d x

\frac{d y}{d x} = 2 x y^{2} + 72 x
