tangent of 12(x-1/x)^4,\at x=2

tangent

y = \frac{405}{2} x - \frac{1377}{4}

Solution steps

Find the tangent point:

(2, \frac{243}{4})

Find the slope of

y = 12 (x - \frac{1}{x})^{4} : \frac{d y}{d x} = 48 (x - \frac{1}{x})^{3} (1 + \frac{1}{x ^{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{405}{2}

Find the line with slope m=

\frac{405}{2}

and passing through

(2, \frac{243}{4}) : y = \frac{405}{2} x - \frac{1377}{4}

y = \frac{405}{2} x - \frac{1377}{4}
