tangent of f(x)=sqrt(x-4),\at x=13

tangent of

f (x) = x - 4, at x = 13

y = \frac{1}{6} x + \frac{5}{6}

Solution steps

Find the tangent point:

(13, 3)

Find the slope of

f (x) = x - 4 : \frac{df ( x )}{d x} = \frac{1}{2 x - 4}

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 = \frac{1}{6}

Find the line with slope m=

\frac{1}{6}

and passing through

(13, 3) : y = \frac{1}{6} x + \frac{5}{6}

y = \frac{1}{6} x + \frac{5}{6}

y^{^{'}} = - \frac{2 x}{y}

\frac{d y}{d x} = \frac{8 x}{5 y}

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

x \to \infty lim (- 5 x^{3})

\int x^{3} - 3 x d x
