    Inequality Modulus
AI Thread Summary
The discussion focuses on solving the inequality involving modulus using the Wavy-Curve method. Key critical points identified are -3, 1, 3, and 5, which create five distinct intervals for analysis. Participants emphasize the importance of simplifying the expression, particularly the term |x| + 1, which is always positive. The conversation highlights the need to evaluate each interval separately to determine where the inequality holds true. Ultimately, the original poster successfully arrives at the solution.

For what values of x is |x|-3 = 0 ?

For what values of x is |x|+1 = 0 ?

Not sure how you're defining critical points, but interesting things will happen at -3, 1, 3 and 5. I would break it into the five ranges those points generate and consider each separately.
But first, there's a very easy simplification. Think about the (|x|+1) term.

Okay I got the answer.
 
I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
