tangent of xy^8+8xy=36,(4,1)

tangent of

x y^{8} + 8 x y = 36, (4, 1)

y = - \frac{9}{64} x + \frac{25}{16}

Solution steps

Find the slope of

x y^{8} + 8 x y = 36 : \frac{d y}{d x} = \frac{- y ^{8} - 8 y}{8 x ( y ^{7} + 1 )}

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{9}{64}

Find the line with slope m=

- \frac{9}{64}

and passing through

(4, 1) : y = - \frac{9}{64} x + \frac{25}{16}

y = - \frac{9}{64} x + \frac{25}{16}
