1/(1 - x^2) > 0
Detail solution
Given the inequality:
11−x2>0\frac{1}{1 - x^{2}} > 0
To solve this inequality, we must first solve the corresponding equation:
11−x2=0\frac{1}{1 - x^{2}} = 0
Solve:
This equation has no roots,
this inequality is executed for any x value or has no solutions
check it
subtitute random point x, for example
x0 = 0

11−02>0\frac{1}{1 - 0^{2}} > 0
1 > 0

so the inequality is always executed
