tangent of y= 8/(x^2+4),(2,1)

tangent of

y = \frac{8}{x ^{2} + 4}, (2, 1)

y = - \frac{1}{2} x + 2

Solution steps

Find the slope of

y = \frac{8}{x ^{2} + 4} : \frac{d y}{d x} = - \frac{16 x}{( x ^{2} + 4 ) ^{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}{2}

Find the line with slope m=

- \frac{1}{2}

and passing through

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

y = - \frac{1}{2} x + 2
