Question

1/(1 + x ^ a + x ^ b) + 1/(1 + x ^ (- a) + x ^ (b - a)) + 1/(1 + x ^ (- b) + x ^ (a - b)) = 1 proof​

Answer 1

Answer:

Given that,

x √ity + y√₁+ x = 0 x √T+y = -4/1+2

Squaring on both sides x²(lty) = y² (1+x) x²+x²y = y² + xy² (x/y) (x+y) = xy(x/y)

x²-y² = xy² - x²y x²³-y²= xy(y-x)

x+y = -xy

(1+x) y =

Differentiating on Both sides with respect to x,

dy (1+x)(x)-xd_(1+x) dx (1+x)² dx dx T- *-(x+1)* (1+x) ² (1+₂)

(₁+x)² dy = 0 dx
