Good evening, I have consulted several precalculus books, intermediate algebra but none of these lists irrational inequalities, trigonometric inequalities and more. In which book I can find them? Thank you :)
jedimath said:Hi, here an example:
$$\sqrt{x+1} + \sqrt{x + 6} > \sqrt{7x + 4}$$
and
$$\frac{4 senx^2 - 1}{2 cosx} >= 0$$
and so on. Yet...inequalites with absolute value.
Thanks.
Many or most precalculus textbooks have problems similar to these, although they would probably be dealing with equations rather than inequalities. The main difference between equations and inequalities is that with inequalities, if you multiply both sides by an expression, the direction of the inequality changes if the expression you're multiplying by is negative.jedimath said:Hi, here an example:

A book about irrational inequalities serves as a resource for understanding and solving mathematical equations involving irrational numbers. It provides techniques and strategies for simplifying and manipulating these types of equations.
This book would benefit anyone who is studying or working in the fields of mathematics, physics, engineering, or any other discipline that involves complex mathematical equations. It can also be useful for students preparing for standardized tests such as the SAT or GRE.
Some common topics covered in a book about irrational inequalities include simplifying and rationalizing irrational expressions, solving equations with irrational solutions, and applying irrational inequalities in real-life situations.
While a basic understanding of algebra and geometry is helpful, most books about irrational inequalities are written in a way that is accessible to readers with varying levels of mathematical background. Some books may also include a review of necessary concepts at the beginning.
Yes, a book about irrational inequalities can serve as a useful reference guide for students and professionals in the mathematical and scientific fields. It can be used to refresh one's memory on certain concepts or to find specific strategies for solving particular types of equations.
