Trigonometric Inequalities


When we found unknown trigonometric function or trigonometric function of some unknown function in at least one member of an inequality we say that this inequality is trigonometric


1) sin x> and sen2 x + tg 2 are trigonometric inequalities.

2) (sen 30º). (x2 - 1) > 0 they are not trigonometric inequalities.

Resolving an inequality as f (x) <g (x), for example, means determining the set s of numbers s, where s is a domain element of f it's from gsuch that f (s) <g (s).

The set s it's called solution set of inequality and every element of s is solution of inequality.

Thus, in the inequality sen x> , the numbers are some of your solutions and the numbers they are not.
