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.Next: Resolving Inequalities (Part 1)
