Answer the question given​

Answer 1

Step-by-step explanation:

The given equation is

$( \frac{x}{a} ) ^{n} + ( \frac{y}{b} )^{n} = 1$

Differentiating both sides w.r.t x,

$\implies \: \frac{n {x}^{n - 1} }{ {a}^{n} } + \frac{n {y}^{n - 1} }{ {b}^{n} } \frac{dy}{dx} = 0$

$\implies \: \frac{n {y}^{n - 1} }{ {b}^{n} } \frac{dy}{dx} = - \frac{n {x}^{n - 1} }{ {a}^{n} }$

$\implies \: \frac{dy}{dx} = - \frac{ {b}^{n} {x}^{n - 1} }{ {a}^{n} {y}^{n - 1} }$

$\frac{dy}{dx}_(a,b) = - \frac{ {b}^{n} {a}^{n - 1} }{ {a}^{n} {b}^{n - 1} }$

$\implies \: \frac{dy}{dx} = - \frac{ b}{a}$

Equation of tangent:

$(y - b) = - \frac{b}{a} (x - a)$

$\implies \: a(y - b) = -b (x - a)$

$\implies \: ay -a b= -bx + ab$

$\implies \: ay + bx = 2 ab$
