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.

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 :)

What Is a rigorous Calculus book? And for algebra Thanks

Yes, I'm Italian. The books in Italian that I have are a little more advanced than those in English. So, for a first approach, I wanted to start with those indicated (or others recommended by you) and then continue with those in Italian. It is also true that from a certain level on, English...

Actually I'm a self-taught person. I'm just a simple fan. For work I do something else. For now it would be enough for me to understand all that are topics of the halliday book. A tipic course of General Physics. :) Sorry for my english. I use google translate.

My goal is to understand Physics and study math needed to it. For now I read some pages to see arguments of the book.

Ho. Which is the best Path to study math & physics? I have Larson Calculus and Halliday Fundamentals of physics. I have know some algebra. No geometry and trigonometry :( Thanks.

Book solution: - We choose the point from which the team athlete ## A ## starts as the origin of the positions. Thus the rider of the square B has an initial position ## S_ {0} = -2.6m ##. - The law of the athlete's position ## A ## is ## s_ {A} = (9.45 m / s) t ##. - The law of the athlete's...

Thanks. So, both solutions (my and that of book) are right? What I would like to understand is why the book uses that method.

Hi, when B receives the baton, he has 85m + 2.6m to run for a total of 87.6m to run. We have this situation, at same instant: - A receives the baton and have 85m to run - B receives the baton and have 87.6m to run The book, for solve the problem, calculate when A and B have same position. At...

NOTE: Sorry for my english. I use Google Translate! Comparing the performance with a friend of mine who is passionate about physics (and he is studying it by himself) we came to the same conclusion. In other words, we have calculated the time taken by both riders to reach the finish line. From...

...I was obviously joking...goooood morning, I am passionate about mathematics and physics and I am reviewing it from scratch. Unfortunately (for you :)) I will write in this forum using google translate because I can't write in English. Thank you all.
