Question

Prove that:

$\frac{1}{1 + {x}^{a - b \: } } + \: \frac{1}{1 + {x}^{b- a\: } } = 1$
​

Answer 1

Answer:

Show that 1/1+x a-b + 1/1+x b-a =1 - 4288612. ... that the roots of the equation (a + b)x² + (b - c) x - (a - b + c) = 0 ... \ div 1 - sinx} + \sqrt{1 - sinx \div 1 + sinx} = 2secx[/tex].
