We now consider an inequality of the form
f1(x) 〉f2(x).
Every numerical value x0 taken from the domain of admissible values is called a solution of the inequality, if, when x0 is substituted into both sides of the inequality, the result is a true numerical inequality. constitute All the the solution solutions of an inequality set of the inequality. 相似文献

The set of real numbers has the property of being ordered: for any numbers a and b we have one and only one of the these relations: a〉b(a is greater than b), a=b, or a〈b(a is less than b). The notation a〉b means the difference a-b is positive; the notation a〈b means the difference a-b is negative. 相似文献
