tangent of f(x)= 1/(sqrt(x)),\at x=4

tangent of

f (x) = \frac{1}{x}, at x = 4

y = - \frac{1}{16} x + \frac{3}{4}

Solution steps

Find the tangent point:

(4, \frac{1}{2})

Find the slope of

f (x) = \frac{1}{x} : \frac{df ( x )}{d x} = - \frac{1}{2 x ^{\frac{3}{2}}}

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}{16}

Find the line with slope m=

- \frac{1}{16}

and passing through

(4, \frac{1}{2}) : y = - \frac{1}{16} x + \frac{3}{4}

y = - \frac{1}{16} x + \frac{3}{4}

\int sin (x) e^{c o s (x)} d x

\int_{0}^{1} 5 x^{2} d x
